🧹 Outside diff range and nitpick comments (47)
Sources/AblyChat/RoomReactions.swift (4)
15-15: Clarify the note regarding receiving your own reaction.In the documentation for
send(params:), the note states:It is possible to receive your own reaction via the reactions subscription before this method returns.
Consider clarifying whether this behavior is guaranteed or merely possible, and explain the conditions under which it occurs to provide better guidance to the users.
33-34: Specify the buffering policy in the return type documentation.In the documentation for
subscribe(bufferingPolicy:), the return type is described as:A subscription
AsyncSequencethat can be used to iterate throughReactionevents.Since the buffering policy affects how the subscription handles incoming events, consider mentioning the buffering policy in the return type documentation for better clarity.
71-83: Provide examples forheadersusage in documentation.The documentation for the
headersproperty inSendReactionParamsprovides a brief explanation. Including examples or use cases can help users understand how to utilizeheaderseffectively, especially in relation to subscription filters.
Line range hint
101-104: IncludeheadersinasQueryItems()for completeness.The
asQueryItems()method currently includes onlytypeandmetadata. Ifheadersare also needed when sending reactions, consider includingheadersin the query items to ensure all parameters are transmitted correctly.Apply this diff to include
headersin the query items:func asQueryItems() -> [String: String] { var dict: [String: String] = [:] dict["type"] = "\(type)" dict["metadata"] = "\(metadata ?? [:])" + dict["headers"] = "\(headers ?? [:])" return dict }Sources/AblyChat/Messages.swift (6)
16-17: Clarify the type ofMessageSubscriptionin the return description.In the documentation for
subscribe(bufferingPolicy:), the return type is described as:A subscription
MessageSubscriptionthat can be used to iterate through new messages.Since
MessageSubscriptionis a custom type conforming toAsyncSequence, consider providing more detail about its behavior or usage in the documentation to aid developers in understanding how to work with it.
28-32: Specify the generic type in the return description forget(options:).In the documentation for
get(options:), the return type is:A paginated result object that can be used to fetch more messages if available.
Consider specifying that the paginated result contains
Messageinstances for clarity.Update the return description to:
A
PaginatedResultcontainingMessageobjects that can be used to fetch more messages if available.
36-46: Explain possible race conditions when sending messages.The note mentions:
It is possible to receive your own message via the messages subscription before this method returns.
Consider elaborating on this behavior to inform users about potential race conditions or the need to handle duplicate messages in their applications.
87-99: Provide examples forheadersusage in message sending.Similar to the
SendMessageParamsdocumentation, including practical examples of how to useheaderscan help developers understand their application in message sending, especially regarding subscription filters.
110-147: Enhance documentation forQueryOptions.Consider adding examples demonstrating how to use
QueryOptionswith different parameters likestart,end,limit, andorderBy. This will assist users in constructing effective queries for fetching messages.
Line range hint
174-212: ImplementSendableconformance correctly inMessageSubscription.The
MessageSubscriptionstruct is intended to beSendable, but it contains a closure propertygetPreviousMessageswhich capturesself, potentially causing issues with Sendable conformance.Ensure that all stored properties in
MessageSubscriptionconform toSendablewithout capturing non-Sendable types orselfin closures. Consider refactoring to eliminate any concurrency problems.Apply this diff to adjust
getPreviousMessages:public struct MessageSubscription: Sendable, AsyncSequence { public typealias Element = Message private var subscription: Subscription<Element> // can be set by either initialiser - private let getPreviousMessages: @Sendable (QueryOptions) async throws -> any PaginatedResult<Message> + private let getPreviousMessages: @Sendable (QueryOptions) async throws -> any PaginatedResult<Message> // Rest of the struct... }Ensure that
getPreviousMessagesdoes not captureselfand that all closures withinMessageSubscriptionare marked as@Sendable.Sources/AblyChat/Presence.swift (5)
Line range hint
26-35: ImprovePresenceCustomDatato handleDoublevalues.Currently,
PresenceCustomDatasupportsIntbut notDouble. If there is a need to handle floating-point numbers in presence data, consider adding support forDouble.Apply this diff to include
Doublesupport:public enum PresenceCustomData: Sendable, Codable, Equatable { case string(String) case number(Int) + case double(Double) case bool(Bool) case null // Update initializers and encoding accordingly... }
Line range hint
71-83: Avoid force unwrapping inasQueryItems()method.In the
asQueryItems()method ofPresenceData, ensure that force unwrapping or forced casting is not used, as it can lead to runtime crashes.Review the implementation to safely handle optional values and casting.
Apply this diff to adjust the method:
func asQueryItems() -> [String: Any] { // Return an empty userCustomData string if no custom data is available guard let userCustomData else { return ["userCustomData": ""] } // Create a dictionary for userCustomData var userCustomDataDict: [String: Any] = [:] // Iterate over the custom data and handle different PresenceCustomData cases for (key, value) in userCustomData { switch value { case let .string(stringValue): userCustomDataDict[key] = stringValue case let .number(numberValue): userCustomDataDict[key] = numberValue + case let .double(doubleValue): + userCustomDataDict[key] = doubleValue case let .bool(boolValue): userCustomDataDict[key] = boolValue case .null: userCustomDataDict[key] = NSNull() } } // Return the final dictionary return ["userCustomData": userCustomDataDict] }Ensure that all cases are handled safely without force unwrapping.
105-114: Clarify error handling inisUserPresent(clientID:).The method documentation specifies that it throws an
ARTErrorInfo. Consider elaborating on the possible errors that can be thrown and under what conditions, to help users handle exceptions appropriately.
147-166: Consolidate subscription methods for presence events.Currently, there are separate methods for subscribing to a single event and multiple events. Consider providing a unified method that accepts a variadic parameter or an array with a default value, simplifying the API.
Example:
func subscribe(events: [PresenceEventType] = [.enter, .leave, .update], bufferingPolicy: BufferingPolicy = .unbounded) async -> Subscription<PresenceEvent>
258-277: Improve documentation forPresenceMemberproperties.Provide more detailed explanations for the
clientID,data,action, andextrasproperties. Including information about how these properties are used and any constraints or noteworthy behaviors.Sources/AblyChat/Rooms.swift (3)
14-18: Clarify the behavior when callinggetduring a release operation.The documentation states:
If a call to this method is made for a room that is currently being released, then it returns only when the release operation is complete.
Consider explaining the rationale behind this behavior and any implications it may have on performance or possible deadlocks, to inform users about potential waits.
Line range hint
81-87: Simplify theOperationTypeenumeration if only used internally.The
OperationTypeenum is used for testing and debug purposes. If it's only for internal use, consider marking it asprivateto prevent unintended external access.
Line range hint
219-267: Review the use of@unknown defaultinPresenceMember.Actionenum.Ensure that the handling of unknown cases is appropriate. Currently, it defaults to
.unknownand prints a message. Consider logging the message using the existing logging mechanism or handling the case according to the project's error handling strategy.Apply this diff to improve unknown case handling:
public enum Action: Sendable { // Existing cases... @unknown default: self = .unknown - print("Unknown presence action encountered: \(action)") + logger.log(message: "Unknown presence action encountered: \(action)", level: .warning) }Sources/AblyChat/Events.swift (2)
3-9: Documentation could be more comprehensiveConsider expanding the documentation to include:
- The relationship with
ARTMessageAction- Available cases and their use cases
- Example usage
Line range hint
11-27: Fix missing return keyword in switch statementThe switch statement is missing explicit return keywords, which could lead to confusion.
Apply this diff:
internal static func fromRealtimeAction(_ action: ARTMessageAction) -> Self? { switch action { case .create: - .create + return .create // ignore any other actions except `message.create` for now case .unset, .update, .delete, .annotationCreate, .annotationDelete, .metaOccupancy: - nil + return nil @unknown default: - nil + return nil } }Sources/AblyChat/Headers.swift (2)
Line range hint
1-8: Ensure consistent number handling with MetadataThe change from NSNumber to Int mirrors the change in Metadata. Consider extracting common documentation about number limitations to a shared location.
Line range hint
1-1: Consider centralizing type improvement TODOsThe TODO referencing issue #13 appears in multiple files regarding type improvements. Consider:
- Creating a central documentation file listing all planned type improvements
- Adding more context about the limitations in the issue
Sources/AblyChat/EmitsDiscontinuities.swift (2)
12-14: Enhance protocol documentation with more contextWhile the documentation follows DocC format, consider enriching it with:
- When/why would a type implement this protocol
- Common use cases or scenarios
- Relationship with discontinuity events
Example enhancement:
/** - * An interface to be implemented by objects that can emit discontinuities to listeners. + * A protocol for types that need to notify listeners about discontinuities in their operation. + * + * Discontinuities typically represent interruptions or breaks in normal operation, such as + * network disconnections or error conditions. Types implementing this protocol can provide + * a way for clients to monitor and react to such events. + * + * Common implementors might include real-time data streams, network connections, or + * any component where temporal consistency is important. */
16-24: Add usage example to method documentationThe documentation structure is good, but would benefit from a concrete example.
Example enhancement:
/** * Subscribes a given listener to a detected discontinuity. * * - Parameters: * - bufferingPolicy: The ``BufferingPolicy`` for the created subscription. * * - Returns: A subscription `AsyncSequence` that can be used to iterate through ``DiscontinuityEvent`` events. + * + * - Example: + * ```swift + * for await event in await connection.onDiscontinuity(bufferingPolicy: .bufferingNewest(1)) { + * if let error = event.error { + * print("Discontinuity detected: \(error.message)") + * } + * } + * ``` */Sources/AblyChat/Reaction.swift (2)
3-11: Enhance type alias documentationWhile documented, the type aliases could benefit from more detailed explanations.
Example enhancement:
/** - * ``Headers`` type for chat reactions. + * Type alias for reaction-specific headers. + * + * This type provides a specialized namespace for headers associated with chat reactions, + * while maintaining compatibility with the base ``Headers`` type. */ public typealias ReactionHeaders = Headers /** - * ``Metadata`` type for chat reactions. + * Type alias for reaction-specific metadata. + * + * This type provides a specialized namespace for metadata associated with chat reactions, + * while maintaining compatibility with the base ``Metadata`` type. */ public typealias ReactionMetadata = Metadata
Line range hint
48-56: Add documentation for initializerThe initializer is missing documentation.
+ /** + * Creates a new reaction with the specified parameters. + * + * - Parameters: + * - type: The type of the reaction + * - metadata: Additional metadata associated with the reaction + * - headers: Headers associated with the reaction + * - createdAt: The timestamp when the reaction was created + * - clientID: The ID of the client that created the reaction + * - isSelf: Whether the reaction was created by the current user + */ public init(type: String, metadata: ReactionMetadata, headers: ReactionHeaders, createdAt: Date, clientID: String, isSelf: Bool) {Sources/AblyChat/Occupancy.swift (1)
25-38: Documentation could be more detailedWhile the documentation follows DocC format, consider enhancing it with:
- For
get(): Document possible error cases that might be thrown- For
channel: Explain common use cases for accessing the underlying channel/** * Get the current occupancy of the chat room. * + * - Throws: An error if the request fails due to network issues or if the room is closed. * - Returns: A current occupancy of the chat room. */ /** * Get underlying Ably channel for occupancy events. * + * This can be useful for advanced use cases such as subscribing to raw channel events + * or accessing channel-specific properties not exposed through the Occupancy interface. * * - Returns: The underlying Ably channel for occupancy events. */Sources/AblyChat/RoomStatus.swift (2)
Line range hint
55-67: Consider using Swift's pattern matching syntax sugarThe
errorproperty implementation could be more concise using Swift's pattern matching.internal var error: ARTErrorInfo? { switch self { - case let .attaching(error): - error - case let .suspended(error): - error - case let .failed(error): - error + case let .attaching(error), + let .suspended(error), + let .failed(error): + error case .initialized, .attached, .detaching, .detached, .releasing, .released: nil } }
Line range hint
69-93: Consider using pattern matching property wrappersThe helper properties could be more concise using Swift's pattern matching property wrappers.
- public var isAttaching: Bool { - if case .attaching = self { - true - } else { - false - } - } + @inline(__always) + public var isAttaching: Bool { + guard case .attaching = self else { return false } + return true + }Sources/AblyChat/Typing.swift (2)
32-42: Consider adding example usage in documentationWhile the documentation for
start()is comprehensive, it would be helpful to include a code example showing typical usage, especially regarding the timer behavior./** * Start indicates that the current user is typing. This will emit a ``TypingEvent`` event to inform listening clients and begin a timer, * once the timer expires, another ``TypingEvent`` event will be emitted. In both cases ``TypingEvent/currentlyTyping`` * contains a list of userIds who are currently typing. * * The timeout is configurable through the ``TypingOptions/timeout`` parameter. * If the current user is already typing, it will reset the timer and being counting down again without emitting a new event. * + * Example: + * ```swift + * try await typing.start() // Starts typing indicator + * // Timer automatically manages typing state + * ``` * * - Throws: An `ARTErrorInfo`. */
Line range hint
66-77: Consider adding Equatable conformanceThe
TypingEventstruct might benefit fromEquatableconformance for testing purposes.-public struct TypingEvent: Sendable { +public struct TypingEvent: Sendable, Equatable {Sources/AblyChat/Message.swift (2)
3-11: Consider adding more context to type alias documentationThe documentation for type aliases could be more descriptive about their purpose and usage.
/** - * ``Headers`` type for chat messages. + * Type alias for message headers, providing additional metadata that can be used + * for filtered subscriptions and other Ably-specific features. */ public typealias MessageHeaders = Headers /** - * ``Metadata`` type for chat messages. + * Type alias for message metadata, allowing arbitrary additional data + * to be attached to messages without server-side validation. */
Line range hint
78-98: Consider adding documentation for the initializerThe public initializer would benefit from documentation explaining parameter requirements and validation.
+ /** + * Creates a new message with the specified parameters. + * + * - Parameters: + * - serial: The unique identifier for the message + * - action: The type of action (created, updated, or deleted) + * - clientID: The ID of the client who created the message + * - roomID: The ID of the room this message belongs to + * - text: The message content + * - createdAt: The timestamp when the message was created + * - metadata: Additional unvalidated data attached to the message + * - headers: Additional headers for filtered subscriptions + */ public init(serial: String, action: MessageAction, clientID: String, roomID: String, text: String, createdAt: Date?, metadata: MessageMetadata, headers: MessageHeaders) {Sources/AblyChat/ChatClient.swift (3)
19-24: Documentation forclientIDshould mention potential nil valueThe documentation for
clientIDshould clarify whether this property can return nil, especially since the implementation inDefaultChatClientis not yet complete.Consider updating the documentation:
/** * Returns the clientId of the current client. * + * This value might be nil if the client is not authenticated or if anonymous authentication is used. * * - Returns: The clientId. */
Line range hint
71-74: ImplementclientIDproperty or mark as unimplementedThe current implementation uses
fatalErrorwhich is dangerous in production code.Consider one of these approaches:
- public nonisolated var clientID: String { - fatalError("Not yet implemented") - } + // Option 1: Return optional + public nonisolated var clientID: String? { + return nil // Until implemented + } + + // Option 2: Add TODO comment + // TODO: Implement clientID property + @available(*, unavailable, message: "Not yet implemented") + public nonisolated var clientID: String { + fatalError("Not yet implemented") + }
81-92: Enhance documentation forlogHandlerandlogLevelThe documentation for logging options should provide more context about default behaviors.
Consider enhancing the documentation:
/** * A custom log handler that will be used to log messages from the client. * - * By default, the client will log messages to the console. + * By default, the client will log messages to the console using Swift's Logger. + * Set this to provide custom logging behavior. */ /** * The minimum log level at which messages will be logged. * - * By default, ``LogLevel/error`` will be used. + * By default, ``LogLevel/error`` will be used. Set this to a lower level + * like ``LogLevel/debug`` to see more detailed logs. */Sources/AblyChat/Logging.swift (2)
17-20: Enhance LogLevel enum documentationThe documentation for LogLevel enum could be more descriptive about when to use each level.
Consider adding more detailed documentation:
/** * Represents the different levels of logging that can be used. + * + * The levels, from most to least verbose, are: + * - ``trace``: Very detailed information for debugging + * - ``debug``: Useful debugging information + * - ``info``: General information about program execution + * - ``warn``: Potentially harmful situations + * - ``error``: Error events that might still allow the application to continue + * - ``silent``: No logging */
Line range hint
95-106: Consider adding documentation for LogLevel mappingThe
toOSLogTypemapping lacks documentation explaining the rationale behind the mapping choices.Consider adding documentation to explain the mapping:
private extension LogLevel { + /// Maps AblyChat log levels to system OSLogType levels. + /// Note: Both debug and trace map to .debug, and both warn and error map to .error, + /// as OSLogType provides fewer granular options. var toOSLogType: OSLogType? { switch self { case .debug, .trace: .debug case .info: .info case .warn, .error: .error case .silent: nil } } }Sources/AblyChat/RoomOptions.swift (3)
55-61: Clarify presence enter mode documentationThe documentation for
enterproperty could be clearer about the implications of setting it to false.Consider updating the documentation:
/** * Whether the underlying Realtime channel should use the presence enter mode, allowing entry into presence. * This property does not affect the presence lifecycle, and users must still call ``Presence/enter()`` * in order to enter presence. + * Setting this to false will prevent users from entering presence mode entirely, and any attempts + * to call ``Presence/enter()`` will result in an error. * Defaults to true. */
83-88: Add units to timeout documentationThe documentation for timeout should consistently mention both seconds and milliseconds since the requirement (CHA-T3) mentions milliseconds.
Consider updating the documentation:
/** * The timeout for typing events in seconds. If ``Typing/start()`` is not called for this amount of time, a stop * typing event will be fired, resulting in the user being removed from the currently typing set. - * Defaults to 5 seconds. + * Defaults to 5 seconds (5000 milliseconds). */
95-100: Add placeholder documentation for empty option structs
RoomReactionsOptionsandOccupancyOptionsstructs should include documentation about their future use.Consider adding more detailed documentation:
/** * Represents the reactions options for a chat room. + * + * Note: This struct is currently a placeholder and will be expanded in future releases + * to include configuration options for room-level reactions. */ public struct RoomReactionsOptions: Sendable, Equatable { public init() {} } /** * Represents the occupancy options for a chat room. + * + * Note: This struct is currently a placeholder and will be expanded in future releases + * to include configuration options for room occupancy tracking. */ public struct OccupancyOptions: Sendable, Equatable { public init() {} }Also applies to: 102-107
Sources/AblyChat/Errors.swift (1)
14-17: Consider updating the TODO comment with more context.The TODO comment about the error code being a guess should include more context about why this particular value was chosen and what considerations should be made when revisiting it.
Sources/AblyChat/Room.swift (5)
3-5: Enhance the Room protocol documentation.The protocol documentation should provide more context about its purpose, typical usage, and relationship with other components. Consider adding:
- Purpose and responsibilities of a Room
- Lifecycle states and transitions
- Required setup and initialization
- Example usage
/** - * Represents a chat room. + * A protocol that represents a chat room, providing real-time messaging, presence tracking, + * and interaction capabilities. + * + * A Room is the central component for chat functionality, managing: + * - Real-time message delivery and history + * - User presence and typing indicators + * - Message reactions and occupancy metrics + * + * Example usage: + * ```swift + * let room = try await chat.getRoom(id: "example-room") + * try await room.attach() + * for await message in room.messages.subscribe() { + * print("New message: \(message.data)") + * } + * ``` */
14-19: Improve messages property documentation.The documentation should better describe the messaging capabilities and common operations.
/** - * Allows you to send, subscribe-to and query messages in the room. + * Provides messaging capabilities for the room, including: + * - Sending new messages + * - Subscribing to real-time message updates + * - Querying message history + * - Retrieving messages by ID * * - Returns: The messages instance for the room. */
21-78: Consolidate and clarify feature-specific documentation.The presence, reactions, typing, and occupancy properties have identical error notes. Consider:
- Creating a shared documentation section about feature enablement
- Clarifying the relationship between onStatusChange overloads
Add a section at the start of the protocol:
/** * Feature Availability * ------------------- * Several Room features (presence, reactions, typing, occupancy) require explicit * enablement through RoomOptions. Attempting to access these features when not * enabled will result in a fatal error. * * To safely check if a feature is enabled: * ```swift * if room.options.presence != nil { * // Presence feature is enabled * await room.presence.enter() * } * ``` */For onStatusChange methods:
-/// Same as calling ``onStatusChange(bufferingPolicy:)`` with ``BufferingPolicy/unbounded``. -/// -/// The `Room` protocol provides a default implementation of this method. +/** + * Subscribes to room status changes using an unbounded buffering policy. + * + * This is a convenience method that calls ``onStatusChange(bufferingPolicy:)`` + * with ``BufferingPolicy/unbounded``. Use this when you want to ensure no status + * changes are missed, at the cost of unbounded memory usage. + * + * - Returns: A subscription that emits room status changes. + * + * - SeeAlso: ``onStatusChange(bufferingPolicy:)`` for custom buffering policies + */
Line range hint
119-136: Enhance RoomStatusChange documentation.The struct documentation should provide more context about its role in room lifecycle management.
/** - * Represents a change in the status of the room. + * Represents a transition between room states, providing both the current and + * previous status for tracking room lifecycle changes. + * + * This type is used by the ``Room/onStatusChange()`` subscription to notify + * observers about room state transitions, such as: + * - Initialization → Attaching + * - Attaching → Attached + * - Attached → Detaching + * - Detaching → Detached + * + * Example usage: + * ```swift + * for await change in room.onStatusChange() { + * print("Room transitioned from \(change.previous) to \(change.current)") + * if change.current == .attached { + * // Room is ready for messaging + * } + * } + * ``` */
87-91: Enhance contributorAnnotations documentation.The property documentation could better explain its role in managing contributor state.
- /// Manager state that relates to individual contributors, keyed by contributors' ``Contributor/id``. Stored separately from ``contributors`` so that the latter can be a `let`, to make it clear that the contributors remain fixed for the lifetime of the manager. + /** + * Manager state that relates to individual contributors, keyed by contributors' + * ``Contributor/id``. This includes: + * - Pending discontinuity events + * - Transient disconnect timeouts + * - Attachment history + * + * Stored separately from ``contributors`` to maintain contributor immutability + * while allowing their associated state to change over the manager's lifetime. + * + * Example annotation: + * ```swift + * ContributorAnnotation( + * pendingDiscontinuityEvent: nil, + * transientDisconnectTimeout: nil, + * hasBeenAttached: true + * ) + * ``` + */

37-39: Ensure default implementation conforms to protocol requirements.
The method func subscribe() async -> Subscription<Reaction> in the protocol RoomReactions should match the default implementation provided in the extension. Verify that both declarations are consistent and correctly conform to Swift's protocol extension rules.
Sources/AblyChat/Messages.swift (1)
20-24: Ensure default implementation conforms to protocol requirements.
The method func subscribe() async throws -> MessageSubscription should align with the default implementation provided in the extension. Verify that both the method signature and error handling are consistent.

30-34: LGTM!
The documentation and implementation are clear and appropriate.
Sources/AblyChat/Metadata.swift (2)
11-21: LGTM! Well-documented security considerations
The documentation clearly explains the purpose and security implications of metadata usage.
Line range hint 1-8: Consider implications of NSNumber to Int change
While changing from NSNumber to Int improves Codable conformance, it might limit the range of numbers that can be stored. Consider documenting these limitations or using Int64 if larger numbers are needed.
✅ Verification successful
Int type limitation appears to be acceptable for current usage
Based on the codebase analysis:
- The number case is primarily used for encoding/decoding JSON data in Presence, Headers, and Metadata
- Current usage shows only basic integer operations without any evidence of large number requirements
- The existing test cases only demonstrate string-based metadata usage
- No JSON examples were found with number values that would exceed Int bounds
The change from NSNumber to Int appears to be a safe improvement for Codable conformance without impacting current functionality. The TODO comment and issue #13 already track future type improvements if needed.

The added DocC dependencies look appropriate. Let's verify there are no known issues with these versions.
✅ Verification successful
Let me gather more information about the dependencies by checking their repositories directly.
DocC dependencies are compatible and up-to-date
The verification shows:
- swift-docc-plugin v1.4.3 is the latest stable release
- No security vulnerabilities were found for these packages
- While swift-docc-symbolkit shows only development snapshots in recent tags, v1.0.0 is a stable release that's commonly used with the DocC plugin

The current documentation is too basic. Consider adding:
- Detailed description of the protocol's purpose and responsibilities
- Usage guidelines and examples
- Requirements for conforming types
- Thread-safety considerations
- Lifecycle management details
/**
- * Represents a chat room.
+ * A protocol that defines the interface for a chat room in the AblyChat system.
+ *
+ * The Room protocol provides functionality for:
+ * - Real-time messaging
+ * - Presence management
+ * - Typing indicators
+ * - Reactions
+ * - Occupancy metrics
+ *
+ * Example usage:
+ * ```swift
+ * let room = try await chatClient.rooms.get(roomID: "my-room")
+ * try await room.attach()
+ * let subscription = await room.messages.subscribe()
+ * for await message in subscription {
+ * print("Received message: \(message.text)")
+ * }
+ * ```
+ *
+ * Thread Safety:
+ * All methods in this protocol are thread-safe and can be called from any thread.
+ *
+ * Lifecycle:
+ * 1. Create using `Rooms.get(roomID:options:)`
+ * 2. Attach using `attach()`
+ * 3. Use features (messages, presence, etc.)
+ * 4. Detach using `detach()`
+ * 5. Release using `Rooms.release(roomID:)`
+ *
+ * Conforming Types:
+ * Types that conform to this protocol must implement all the required properties
+ * and methods while ensuring thread-safety and proper error handling.
*/21-54: Clarify error prevention in feature-specific properties.
The documentation mentions that accessing disabled features is a programmer error but doesn't explain how to check if they're enabled.
/**
* Allows you to subscribe to presence events in the room.
*
* - Note: To access this property if presence is not enabled for the room is a programmer error, and will lead to `fatalError` being called.
+ *
+ * You can check if presence is enabled by examining the room options:
+ * ```swift
+ * if room.options.presence != nil {
+ * // Safe to access room.presence
+ * }
+ * ```
*
* - Returns: The presence instance for the room.
*/Also applies to: reactions, typing, and occupancy properties.

Consider using associated values for error states
The current implementation requires optional unwrapping of errors. Consider using associated values in the ConnectionStatus enum for error states, similar to how RoomStatus implements this pattern.
Example implementation:

44-45: Convert inline comments to Swift documentation formatThe inline comments (CHA-CS1*) appear to be copied from JavaScript documentation. Convert these to proper Swift documentation format for consistency.
Example conversion:
- // (CHA-CS1a) The INITIALIZED status is a default status when the realtime client is first initialized. This value will only (likely) be seen if the realtime client doesn't have autoconnect turned on. + /** + * The default status when the realtime client is first initialized. + * This value will likely only be seen if the realtime client doesn't have autoconnect enabled. + */Also applies to: 51-52, 58-59, 65-66, 72-73, 79-80

274-284: Consider documenting the workaroundThe comment about
ARTRealtimePresenceQueryand Swift 6 compatibility is important implementation detail that should be properly documented using DocC syntax.-// Originally, ``Presence/get(params:)`` accepted an ARTRealtimePresenceQuery object, but I've changed it to accept this type, because else when you try and write an actor that implements ``Presence``, you get a compiler error like "Non-sendable type 'ARTRealtimePresenceQuery' in parameter of the protocol requirement satisfied by actor-isolated instance method 'get(params:)' cannot cross actor boundary; this is an error in the Swift 6 language mode". +/// Originally, ``Presence/get(params:)`` accepted an `ARTRealtimePresenceQuery` object, but was changed to accept this type due to Swift 6 actor isolation requirements. +/// +/// - Note: This is a temporary workaround until we better understand Swift's region-based isolation.

307-330: Consider using string interpolation for error messagesThe error messages could be more maintainable using string interpolation with raw strings.
Example for one case:
- "Rooms.get(roomID:options:) was called with a different set of room options than was used on a previous call. You must first release the existing room instance using Rooms.release(roomID:). Requested options: \(requested), existing options: \(existing)" + """ + Rooms.get(roomID:options:) was called with a different set of room options \ + than was used on a previous call. You must first release the existing room \ + instance using Rooms.release(roomID:). \ + Requested options: \(requested), existing options: \(existing) + """Sources/AblyChat/Room.swift (2)
7-11: Add examples and constraints to roomID documentation.Consider enhancing the documentation with:
- Example of a valid room identifier
- Any constraints on the identifier format
- Whether the identifier is case-sensitive
/** * The unique identifier of the room. * + * The room identifier must follow these rules: + * - Must be non-empty + * - Must be URL-safe + * - Case-sensitive + * + * Example: + * ```swift + * let roomID = "my-chat-room-123" + * ``` + * * - Returns: The room identifier. */
79-91: Add example usage with error handling.The documentation thoroughly explains the behavior but would benefit from:
- Example code showing proper error handling
- Cross-references to related status types using
RoomStatussyntax/** * Attaches to the room to receive events in realtime. * * If a room fails to attach, it will enter either the ``RoomStatus/suspended(error:)`` or ``RoomStatus/failed(error:)`` state. * * If the room enters the failed state, then it will not automatically retry attaching and intervention is required. * * If the room enters the suspended state, then the call to attach will throw `ARTErrorInfo` with the cause of the suspension. However, * the room will automatically retry attaching after a delay. * + * Example: + * ```swift + * do { + * try await room.attach() + * } catch let error as ARTErrorInfo { + * switch await room.status { + * case .failed: + * // Handle permanent failure + * case .suspended: + * // Will automatically retry + * default: + * // Handle other errors + * } + * } + * ``` * * - Throws: An `ARTErrorInfo`. */

4-6: LGTM: Documentation follows DocC guidelines
The documentation is clear and properly uses DocC-style symbol links.
Line range hint 142-166: LGTM: Well-structured error handling with proper status code mapping
The implementation correctly maps error codes to status codes following the Chat-specific Error Codes specification. The separation between fixed and variable status codes is clean and maintainable.
Let's verify the status code mappings against the specification:
Also applies to: 188-207
✅ Verification successful
Based on the search results, I can now generate a final response since we have sufficient context from the error code definitions. The code shows that the error codes and their mappings are well-defined in the codebase, with proper numeric values assigned (e.g., badRequest = 40000, messagesAttachmentFailed = 102001, etc.).
LGTM: Status code mappings are correctly implemented
The implementation follows a clear pattern where:
- 400 status code is correctly mapped to client-side errors (badRequest, roomInFailedState, etc.)
- 500 status code is properly mapped to server/attachment failures (messagesAttachmentFailed, presenceAttachmentFailed, etc.)
The error code structure is well-organized with:
- Distinct numeric error codes (40000, 102001, etc.)
- Clear separation between fixed and variable status codes via
ErrorCodeAndStatusCodeenum - Proper mapping of feature-specific errors to their respective status codes

12-15: Consider implementing associated values for error states
The TODO comment about error unwrapping could be addressed by using associated values in the ConnectionStatus enum, similar to RoomStatus.

WIP for #1. What's here so far:
58a4fa2; the first few documentation comments are copied across with some light editing to match the Swift documentation syntax, but when it started to become clear that we were going to need deeper edits for a bunch of stuff I switched over to copying them over without any editing; we will have to do a second pass for editing.
