変更履歴: Twilio Chat iOS SDK

We intend to sunset the Programmable Chat API on July 25, 2022 to focus on the next generation of chat: the Twilio Conversations API. Find out about the EOL process. We have also prepared this Migration Guide to assist in the transition from Chat to Conversations.

Latest release: 5.0.1

We recommend referencing the links below in your projects. As we patch bugs, these links will automatically be updated with fixes.

If you need help installing these frameworks in your project, see our installation guidance.

The Chat iOS SDK is unavailable via Carthage because we require support for binary XCFramework files.

If you are interested in Mac Catalyst support, please contact support to get hands-on experience with it.

Support for Previous Versions of the Chat SDKs

Twilio Programmable Chat SDKs use Semantic Versioning. Twilio supports version N-1 for 12 months after the first GA release of version N. We recommend that you upgrade to the latest version as soon as possible to avoid any breaking changes. Version 5.x is the latest iOS version.

Support for 4.x will cease on May 17, 2022. Please upgrade to the latest version.

Support for 3.x ceased on July 20, 2021. Please upgrade to the latest version.

Support for 2.x ceased on March 6, 2021. Please upgrade to the latest version.

End-of-Life for 1.x occurred on June 30, 2019. Please upgrade to the latest version.

破壊的変更

  • Major under-the-hood improvement (the “Sessionless” protocol). This improvement is designed primarily for improved reliability. While this is not a breaking code change, it does carry a meaningful impact on timing:
    • SDK commands will return success or failure up to ~10% more quickly than before.
    • Real-time updates of data are now likely to arrive after the command completes.
      For example, [TCHChannel setAttributes] will invoke completion (i.e., success) while [TCHChannel attributes] still returns the old value. To see the new value, we recommend waiting for an update event, e.g., in the chatClient:channel:updated:TCHChannelUpdateAttributes delegate.
  • The channel list page size increased from 50 to 100. Please make sure your code respects any returned page size, rather than assuming 50 (or 100).
  • Some error messages have changed:
    • Declining an invite while already joined will return an error 50601, Invite not found instead of 50602, Cannot decline invite when already channel member.
    • Trying to leave a channel you're not part of will return error 50402, Member not found instead of 50400, User not member of channel.

  • sha256: 57906c180c5e5bf6fa1fee68ae53fff3971978dccecd66de29ab00b1a3fb4e3e

変更点

  • The SDK now supports HTTP proxy. Proxy is enabled with a new flag useProxy passed to client properties on client creation. Proxy settings are read from the system configuration.
  • Added the ability to defer certificate checks to the OS (disable pinning) using a new flag, deferCertificateTrustToPlatform, passed to client properties on client creation.
  • A callback from withAttributes on message options creation will be called now after a message would be sent.

既知の問題

変更点

  • Fixed a bug when onChannelDeleted doesn't come for private Channel when Member removed by other user.
  • Fixed a bug which could lead to client synchronisation stuck.
  • Fixed a crash on accessing memberWithIdentity from multiple threads.

Programmable Chat iOS 4.0.1 (October 21, 2020)

変更点

  • Fixed a bug which could lead to crashes on member attributes update.

Programmable Chat iOS 4.0.0 (July 20, 2020)

破壊的変更

  • Renamed TCHMessage accessor: timestamp as dateCreated; timestampAsDate asdateCreatedAsDate.
  • Asynchronous [TCHMembers membersWithCompletion] transformed to synchronous [TCHMembers membersList].
  • Added TCHMemberUpdateLastConsumptionTimestamp.
    • This as a result also changed value of TCHMemberUpdateAttributes, potentially a silent breaking change if this value was serialized.
  • Changed TWSMap/TWSList queryItemsWithOptions to return error in completion if pageSize is 0.
  • Changed [TCHChannel getUnconsumedMessagesCountWithCompletion] to return nil instead of 0 if message consumption horizon was not set.
    • Completion now uses NSNumber* (nullable object type), instead of NSUInteger to accommodate this change.
  • Changed [TCHMessages setNoMessagesConsumedWithCompletion] to use nullable NSNumber*, it will always return nil (because it resets the consumption horizon).

変更点

  • Added [TCHMessage getMediaContentTemporaryUrlWithCompletion] to get a temporary direct link to Media content.
  • To download Media by direct URL, use native iOS API, such as [NSData dataWithContentsOfURL()].
  • Deprecated [TCHMessage getMediaWithOutputStream:...]. Use above API instead.

Programmable Chat iOS 3.1.1 (June 1, 2020)

変更点

  • Fixed the bug when connection is dropped with message: "The WebSocket message exceeded the locally configured limit".

Programmable Chat iOS 3.1.0 (May 20, 2020)

  • Improved stability on shutdown, fixed crash issues.

Programmable Chat iOS 3.0.1 (March 12, 2020)

Programmable Chat iOS 3.0.0 (March 6, 2020)

破壊的変更

  • Dropped iOS v9, v10 support. Minimum iOS version now is 11.0
  • Added type-safe interface TCHJsonAttributes for Attributes (TCHChannel, TCHMessage, TCHMember, TCHUser). Now it supports not only Json Object, which was translated to NSDictionary, but also NSArray, NSString, NSNumber, NSNull.

変更点

  • Fixed a bug when channel attributes are empty when chatClient:channelAdded: called.
  • Fixed an issue when sometimes connecting events don’t arrive.
  • Fixed incorrect behaviour when user identity contained some special symbols.
  • New type of error TCHClientConnectionStateFatalError could appear in some cases. This error means chat is in a terminal state, and needs to re-create the client.
