Change log

All notable changes to the LaunchDarkly Swift EventSource library will be documented in this file. This project adheres to Semantic Versioning.

3.3.0 (2024-05-31)

Features

  • adds ability to provide a OSLog instance via the Config.logger property (c10ec29)
  • adds ability to provide a OSLog instance via the Config.logger property (#78) (2220929)

3.2.0 (2023-12-29)

Features

  • Add Compilation & Testing On Windows (#68) (ac5f18c)

[3.1.1] - 2023-06-12

Fixed:

  • Per the SSE spec, an HTTP 204 will now halt retry attempts by default.

[3.1.0] - 2023-06-05

Changed:

  • Enforce TLS v1.2 as a required minimum.

Fixed:

  • Fix re-entrancy issue with start command. (Thanks, g-mark!)

[3.0.0] - 2022-10-06

Changed

  • Dropped support for older versions in accordance with the new Xcode 14 release.

[2.0.0] - 2022-08-29

Changed

  • The CI build now incorporates the cross-platform contract tests defined in https://github.com/launchdarkly/sse-contract-tests to ensure consistent test coverage across different LaunchDarkly SSE implementations.
  • Removed explicit typed package products. Thanks to @simba909 for the PR (#48).

[1.3.1] - 2022-03-11

Fixed

  • Fixed a race condition that could cause a crash when stop() is called when there is a pending reconnection attempt.

[1.3.0] - 2022-01-18

Added

  • Added the configuration option urlSessionConfiguration to EventSource.Config which allows setting the URLSessionConfiguration used by the EventSource to create URLSession instances.

Fixed

  • Fixed a retain cycle issue when the stream connection is ended.
  • Removed deprecated VALID_ARCHS build setting from Xcode project.
  • Unterminated events will no longer be dispatched when the stream connection is dropped.
  • Stream events that set the lastEventId will now record the updated lastEventId even if the event does not generate a MessageEvent.
  • Empty stream "data" fields will now always record a newline to the resultant MessageEvent data.
  • Empty stream "event" fields will result in now result in the default "message" event type rather than an event type of "".

[1.2.1] - 2021-02-10

Added

  • SwiftLint configuration. Linting will be automatically run as part of the build if Mint is installed.
  • Support for building docs with jazzy. These docs are available through GitHub Pages.

Fixed

  • Reconnection backoff was always reset if the previous successful connection was at least backoffResetThreshold prior to the scheduling of a reconnection attempt. The connection backoff has been corrected to not reset after the first reconnection attempt until the next successful connection. Thanks to @tomasf for the PR (#14).
  • On an UnsuccessfulResponseError the configured connectionErrorHandler would be called twice, the second time with a URLError.cancelled error. Only if the second call returned ConnectionErrorAction.shutdown would the EventSource client actually shutdown. This has been corrected to only call the connectionErrorHandler once, and will shutdown the client if ConnectionErrorAction.shutdown is returned. Thanks to @tomasf for the PR (#13).
  • A race condition that could cause the EventSource client to restart after shutting down has been fixed.

[1.2.0] - 2020-10-21

Added

  • Added headerTransform closure to LDConfig to allow dynamic http header configuration.

[1.1.0] - 2020-07-20

Added

  • Support arm64e on appletvos, iphoneos, and macosx SDKs by extending valid architectures.
  • Support for building LDSwiftEventSource on Linux. Currently this library will not generate log messages on Linux, and may not behave correctly on Linux due to Foundation being incomplete.

[1.0.0] - 2020-07-16

This is the first public release of the LDSwiftEventSource library. The following notes are what changed since the previous pre-release version.

Changed

  • Renamed EventHandler.onMessage parameter event to eventType.
  • The EventSource class no longer extends NSObject or URLSessionDataDelegate to not expose urlSession functions.

[0.5.0] - 2020-07-14

Changed

  • Default LDSwiftEventSource product defined for the SwiftPM package is now explicitly a dynamic product. An explicitly static product is now available as LDSwiftEventSourceStatic.

[0.4.0] - 2020-07-13

Changed

  • Converted build system to use a single target to produce a universal framework, rather than separate targets for each platform that share a product name. This is to prevent issues with xcodebuild resolving the build scheme to an incorrect platform when building dependent packages with 'Find Implicit Dependencies' enabled. This is due to a bug in xcodebuild, for more information see http://www.openradar.me/20490378 and http://www.openradar.me/22008701.

[0.3.0] - 2020-06-02

Added

  • Added stop() method to shutdown the EventSource connection.

Changed

  • Logging subsystem renamed from com.launchdarkly.swift-event-source to com.launchdarkly.swift-eventsource

[0.2.0] - 2020-05-21

Added

  • Public constructors for UnsuccessfulResponseError and MessageEvent to allow consumers of the library to use them for unit tests.

[0.1.0] - 2020-05-09

Added

  • Initial implementation for internal alpha testing.
