Equatableenhances the usability of theOccupancyOptionsstruct in contexts where equality checks are necessary.Tests/AblyChatTests/Mocks/MockRealtime.swift (1)
18-25: LGTM!The
createmethod is correctly implemented and enhances the usability of theMockRealtimeclass.Sources/AblyChat/Room.swift (2)
1-1: LGTM!The
@preconcurrencyimport statement is correctly used to indicate that the imported module does not support concurrency.
Line range hint
2-18: LGTM!The
Roomprotocol is correctly defined and provides a clear contract for room implementations.Sources/AblyChat/Rooms.swift (2)
1-1: LGTM!The
@preconcurrencyimport statement is correctly used to indicate that the imported module does not support concurrency.
2-8: LGTM!The
Roomsprotocol is correctly defined and provides a clear contract for room implementations.Tests/AblyChatTests/DefaultRoomsTests.swift (3)
6-21: LGTM!The test function
test_get_returnsRoomWithGivenIDis well-written and covers the expected behavior.
24-38: LGTM!The test function
test_get_returnsExistingRoomWithGivenIDis well-written and covers the expected behavior.

1-8: LGTM!The error domain definition is correct and follows best practices.
10-26: LGTM! But revisit the TODO comment.The
ErrorCodeenum is well-defined. However, the TODO comment indicates that the error code and status code are guesses and need to be revisited. Ensure that this is tracked and addressed in the future.
29-52: LGTM!The
ChatErrorenum is well-defined and provides useful metadata for the error.
54-67: LGTM! But revisit the TODO comment.The extension for
ARTErrorInfois well-defined. However, the TODO comment indicates that the implementation needs to be revisited once the related issue inably-cocoais resolved. Ensure that this is tracked and addressed in the future.

6-6: LGTM! But verify theMockRealtime.create()method.The change in the instantiation method for
MockRealtimesuggests an enhancement in the setup or configuration encapsulated within thecreate()method. Ensure that thecreate()method aligns with the intended behavior of the test.The code changes are approved.
Run the following script to verify the

Verification Successful:
MockRealtime.create()Method ExistsThe
MockRealtime.create()method is correctly implemented in theTests/AblyChatTests/Mocks/MockRealtime.swiftfile. It returns an instance ofMockRealtimeinitialized with an empty key, which aligns with the intended behavior for testing. No further action is needed.

Part of #19. References to spec are based on [1] at commit aa7455d. I’ve decided to, for now, throw ably-cocoa’s ARTErrorInfo for consistency with JS; created #32 to revisit this later. We have decided (see [3]) that we’re going to try using actors as our mechanism for concurrency-safe management of mutable state. We accept that this will lead to more of the public API needing to be annotated as `async` (as has happened to Rooms.get here), which in some cases might lead to weird-looking API, and have chosen to accept this compromise in order to get the safety checking offered to us by the compiler, and because of developers’ aversion to writing "@unchecked Sendable". We might not have needed to make this compromise if we had access to Swift 6 / iOS 18’s Mutex type, which allows for synchronous management of mutable state in a way that the compiler is happy with. But, none of the decisions here need to be final; we can see how we feel about the API as it evolves and as our knowledge of the language grows.

This is preparation for storing a realtime client inside the Chat SDK’s Sendable client types. The Sendable requirement added here will be satisfied by ably-cocoa’s ARTRealtime once [1] is resolved. [1] ably/ably-cocoa#1962
