iOS Core SDK

Enhancements

• Room joins are up to 25% faster under normal network conditions
• Improved the initial quality of video received from mobile participants

Fixes

• Fixed a crash when switching between breakout rooms
• When unmuting audio or video, the SDK now requests permission when the corresponding RtkMeetingInfo.enableAudio or RtkMeetingInfo.enableVideo field is false. The UI Kit component is no longer silently disabled.

Breaking changes

• Plugins are no longer provided by the server. They must now be declared upfront on the client side by passing a plugins list to RtkMeetingInfo. Any plugin not declared at initialization will not be available in the meeting.

  let meetingInfo = RtkMeetingInfo(
    authToken: authToken,
    plugins: [
      RtkClientPluginConfig(
        id: "whiteboard", // Must match the plugin ID used on Web for sync to work
        name: "Whiteboard",
        url: "https://example.com",
        icon: "https://example.com/logo.png",
        permissions: RtkClientPluginPermissions(canActivate: true, canDeactivate: false)
      )
    ]
  )
  

• Several internal properties have been removed from RtkPlugin: baseURL, config, description, isPrivate, and staggered. Use the new icon and permissions properties instead.
• baseUrl in RtkMeetingInfo now has a default value and no longer needs to be passed explicitly.
• The two-argument subscribe(key:listener:) and unsubscribe(key:listener:) overloads on RtkStore that passed both the key and value to the callback have been removed. Use the single-argument callback variants introduced in 2.1.0.

Features

• AI Transcription A new RtkAi class (exposed as client.ai) provides access to real-time transcripts. Implement RtkAiEventListener and register it with addAiEventListener(_:) to receive onTranscript(data:) callbacks. A transcriptionEnabled permission is available on MiscellaneousPermissions.
• Connected Meetings (Breakout Rooms) A new RtkConnectedMeetings class (exposed as client.connectedMeetings) enables breakout room workflows. Register an RtkConnectedMeetingsEventListener to handle room transitions and state updates. See the Breakout Rooms documentation for a full guide.
• Chat: Edit and Delete Messages can now be edited and deleted. New methods on RtkChat: editTextMessage(messageId:newText:onResult:), editImageMessage(messageId:newUri:onResult:), editFileMessage(messageId:newUri:onResult:), and deleteMessage(messageId:onResult:). RtkChatEventListener gains onMessageEdited(message:) and onMessageDeleted(messageId:) callbacks. ChatMessage now includes an isEdited flag.
• Chat: Fetch and Pagination New methods on RtkChat fetchPublicMessages(beforeTimestamp:count:onlyPinned:onResult:), fetchPrivateMessages(userId:beforeTimestamp:count:onlyPinned:onResult:), fetchPinnedMessages(beforeTimestamp:count:onlyPinned:onResult:), and getMessages(timestamp:count:channelId:isPinned:onResult:) allow fetching historical messages with cursor-based pagination via FetchMessagesResult(messages:hasMore:).
• Client-Declared Plugins Plugins are now configured entirely on the client via RtkClientPluginConfig and RtkClientPluginPermissions. RtkPlugin exposes the new icon and permissions properties accordingly.
• Targeted Broadcast Messages RtkParticipants.broadcastMessage(message:targetParticipantIds:payload:) sends a message to a specific subset of participants.
• Nullable Store Values RtkStore.set(key:value:broadcast:persist:) now accepts a nullable value: Any?, allowing keys to be cleared by setting them to nil.
• Logging Control RealtimeKitClient gains enableLogging(_:) and enableLogging(_:minSeverity:) to control SDK log output at runtime.
• Result_ Utility Type A new Result_<S, F> type with Success and Failure variants is used consistently across new async APIs. It is named Result_ to avoid collision with Swift's built-in Result type.

Fixes

• Improved reconnection handling to ensure media recovers gracefully in more scenarios
• Fixed potential UI hangs by dispatching audio route change observer off the main thread
• Improved simulcast tiers to broadcast at a wider range of qualities on higher tiers
• Fixed some races in media handling causing mute/unmute operations to rarely result in a crash
• Optimized API calls in the room join flow to speed up first join durations
• Fixed file and image uploads in chat failing under some conditions

Breaking changes

• RtkParticipants.activeSpeaker RtkParticipants.lastActiveSpeaker. The old activeSpeaker property is deprecated and will be removed in a future release.
• RtkSelfParticipant.enableScreenShare() enableScreenShare(onResult:). The old no-callback version is deprecated and will be removed in a future release.
• RtkSelfParticipant.disableScreenShare() disableScreenShare(onResult:). The old no-callback version is deprecated and will be removed in a future release.
• RtkStore.subscribe(key, (key, value) Unit) subscribe(key, (value) Unit). The old two-argument callback signature is deprecated but remains functional via a backward-compatible shim.
• RtkStore.unsubscribe(key, (key, value) Unit) unsubscribe(key, (value) Unit). The old two-argument callback signature is deprecated but remains functional via a backward-compatible shim.

Features

• Added RtkChat.pin() and RtkChat.unpin() methods to pin and unpin chat messages
• Added RtkChat.getMessagesByUser() to filter messages by sender and RtkChat.getMessagesByType() to filter messages by type
• Added SelfPermissions.canPinMessage() to check whether the local participant has permission to pin messages

Fixes

• Fixed recording state getting stuck as "recording" when stopping a recording that was started by another participant
• Fixed "ghost" participants appearing on the grid when a user was on the setup screen but had not yet joined the socket room
• Fixed webinar host being invisible to other participants when joining late
• Fixed recording bots and other hidden participants incorrectly appearing on the participant grid
• Fixed waitlisted participants appearing in the participant list before being admitted to the meeting

Breaking changes

• Removed Hive SFU support. Only the Cloudflare SFU is supported going forward.

• Existing APIs related to middlewares were removed and replaced with equivalent counterparts from WebRTC: RtkSelfParticipant#addVideoMiddleware, RtkSelfParticipant#getVideoMiddlewares and RtkSelfParticipant#removeVideoMiddleware were removed. We do not support middlewares on iOS so these APIs were no-op and were incorrectly exposed.
