Synopsis of enhancements:

• flowId has been deprecated in favor of using the completion blocks already present in the SDK.
• The distinction between remote (for remotely initiated operations) and result (for locally initiated operations) has been transitioned to TWSEventContext's isLocal property. You will receive a call to the now shared delegate methods with this object where it is applicable. For Lists and Maps, local operations previously provided the delegate call with only the index or key for the item – the full item will now be returned for both local and remote operations.
• Documents, Lists (and their items), Maps (and their items) and Streams may now all have an optional max time to live specified. This number is expressed in seconds and is relative to when the TTL is set. After the TTL expires, the object will be destroyed on the backend in the near future. TWSOpenOptions has been expanded to allow specifying a TTL during object creation (this property is ignored when opening preexisting objects). The TWS*Metadata classes taken as a parameter for some methods on Document, List and Map are optional and can be specified as nil.

Migration tips:

flowID has been removed globally; most places that previously accepted a flowID now accept metadata which can be nil today if you are not specifying a TTL.

Most delegate methods have changed signature. This is important to note since legacy delegate methods will generally not produce any warnings or errors with this change. The individual remote and local delegate methods have been combined into a single delegate method for operations. Delegates which previously received only an index or key will now receive the full value. Most delegate methods now also provide a TWSEventContext object which will indicate whether the operation was locally or remotely initiated.

Update squashing:

Individual local operations will continue to return the status of each operation via their completion block but updates sent to the server may be batched for efficiency. This means remote clients may not see every state update performed individually, but will instead see updates with the object's final updated state.

If you require updates to be treated as individual operations for purposes of notifying remote clients, it is recommended you schedule subsequent updates to occur after the completion of each operation.

Specific changes to classes:

• TWSConstants
  • typedef TWSDuration (NEW)
  • constant TWSDurationInfinity (NEW)
  • block TWSDataMutator no longer takes a flowId parameter (CHANGED)
• TWSOpenOptions
  • - (TWSOpenOptions *)ttl:(TWSDuration)ttl (NEW)
  • - (TWSDuration)ttl (NEW)
• TWSEventContext (NEW)
  • Added to provide context to your delegate about the operation performed. Today, this includes an isLocal property which will return true if the operation was initiated by the local client, false if initiated remotely.
• TWSDocument
  • Added -setTtl:completion: method
  • Removed flowID references, added TWSDocumentMetadata for specifying initial TTL.

変更点

• Introduced TWSTwilioClientCompletion as a parameter to client creation. Clients are no longer created as immediate returns, instead the completion block is called when the client is available and ready for use.
• updateToken accepts a completion block now to indicate the success or failure of the token update operation.
• Added optional TWSSynchronizationStrategy (with values TWSSynchronizationStrategyDefault and TWSSynchronizationStrategyAggressive) to TWSOpenOptions.
• Remotely changed items within Maps no longer are notified via a single set delegate method but instead distinct added and updated delegate methods to convey which operation occurred.
• Sync SDK log output is now prefixed with TWSY for easier evaluation of logs.
• Deprecation of distinct uniqueName accessor on TWSOpenOptions - the set value will be available via the sidOrUniqueName accessor.

• ドキュメント

変更点

• Resolved potential incompatibility with other Twilio SDKs in the same project.
• Updated framework signing for AppStore compatibility.
• The endpoint_id identifier specified in access tokens is now automatically generated and persisted in the keychain. The following should be observed with this change:
  • endpoint_id is no longer a required identifier in your generated access tokens, you may omit it from this build forward.
  • endpoint_id will be ignored if specified with your access token.
  • When running in the iOS simulator only, the automatically generated endpoint_id may not persist between runs to the simulator keychain without this [work-around].
• If a client is initially created with an invalid access token, creation will fail and nil will be returned for the client instance.
• Added new error callback to SyncClient: - (void)syncClient:(nonnull TwilioSyncClient *)client errorReceived:(nonnull TWSError *)error; will be called in case of client failures, for example when using an invalid access token.
