9.2.0 - 2021-01-15

Fixed

  • The subscribed parameter on a PusherChannel is now set to false when calling unsubscribe(_ channelName: String).
  • Enhanced thread safety for common operations: subscribing / unsubscribing with channels, and binding / unbinding with events.

9.1.1 - 2020-12-15

Fixed

  • Resolved a race condition that could prevent automatic reconnection attempts in certain circumstances.

9.1.0 - 2020-12-07

Added

  • Encrypted channels are now support by default by the PusherSwift target.
  • Encrypted channels are now supported if integrating the SDK via Swift Package Manager.
  • tvOS as a target platform is now supported regardless of if encrypted channels are used.
  • tweetnacl-swiftwrap is now a dependency.

Changed

  • Migrated the WebSocket client code to use our NWWebSocket library.
  • Improvements to WebSocket reconnection functionality for unstable connections, or connections which migrate from Wi-Fi to Cellular (or vice versa).

Removed

  • The PusherSwiftWithEncryption target has been removed.
  • Reachability is no longer a dependency.

9.0.0 - 2020-10-09

Added

  • Connects to Pusher servers using a WebSocket client that is fully-native code.
  • Pusher Channels Protocol closure codes are now respected when attempting to reconnect to Pusher servers after a disconnection.

Changed

  • The autoReconnect option is now ignored if a received closure code is from the Channels Protocol closure code range.

  • Removed BETA label for Private encrypted channels feature in the README.

Removed

  • Starscream is no longer a dependency.

8.0.0 - 2020-04-27

Added

  • Added support for end-to-end encryption. There is a new target: PusherSwiftWithEncryption and a new dependency for that target Sodium. The original PusherSwift target does not require Sodium and has all the same features as PusherSwiftWithEncryption except the ability to decrypt events. You can find details about how to use PusherSwiftWithEncryption in the README. As part of this feature, there is a new function in the PusherDelegate: failedToDecryptEvent, and channel names prefixed with private-encrypted- are now interpreted as encrypted channels in both targets.

Changed

  • The encrypted parameter for PusherClientOptions has been renamed to useTLS. Its behavior and default value (true) are unchanged.
  • Updated to Swift 5.0 and updated dependencies (@JonathanDowning).

Removed

  • CryptoSwift is no longer a dependency.

7.2.0 - 2019-10-18

Added

Fixed

  • Fixed a compilation warning caused by incorrect parameter names in documentation comments (@funkyboy).

7.1.0 - 2019-10-03

Added

  • Added new bind functions which accept a callback that receives a PusherEvent. A PusherEvent represents an event received from the websocket and has properties containing the event name, channel name and data. In addition, PusherEvent has a new property, userId, which allows you to verify the ID of the user who triggered a client event on a presence channel. You can read more about this feature in the docs. All the old bind functions are still available for backwards compatibility. The data property of PusherEvent is not automatically parsed from JSON and you can decide to parse that as required. The parsing behavior is unchanged for data passed to callbacks bound by the old bind functions.

Changed

  • Updated the deployment targets so they are consistent regardless of whether you import the library using CocoaPods or Carthage.

7.0.0 - 2019-04-16

Changed

  • Updated to Swift 4.2.
  • Updated dependencies to newer versions, but pinned dependencies before any Swift 5 versions for compatibility with older versions of Xcode (@cowgp).

Removed

  • Removed push notifications beta (replaced by Pusher Beams which has its own libraries).
  • Removed TaskQueue dependency (used by push notifications beta).

Fixed

  • Fixed issues compiling the library with Swift 5/Xcode 10.2.
  • Fixed issue related to the capturing of self in Reachability callbacks (@PorterHoskins).
  • Fixed unreliable tests.

6.1.0 - 2018-05-18

Changed

  • Reverted to using upstream version of Starscream instead of fork.

6.0.0 - 2018-04-04

Added

  • Client will now send a ping to the server if there has been a period of inactivity on the socket. This should help detect some disconnections that previously weren't being noticed.

Changed

  • All dependencies are now defined to be brought in using the appropriate package manager (Carthage or CocoaPods)
  • Reconnection strategy has been changed to now attempt reconnecting indefinitely, with an exponential backoff but a maximum interval of 120 seconds between reconnection attempts.

Removed

  • Removed the deprecated AuthRequestBuilderProtocol function: func requestFor(socketID: String, channel: PusherChannel) -> NSMutableURLRequest?
  • reconnectingWhenNetworkBecomesReachable connection state
