Enhancements

• Minimum supported iOS deployment target for the Twilio Video SDK is set to iOS 12.2. This version is built with Xcode 15.3.0.

• The SDK now also comes in the static XCFramework format. Follow the steps to add the static lib to your iOS app:

  • Drag and drop the TwilioVideo.xcframework extracted from TwilioVideo-static.xcframework.zip into the Xcode project.
  • In Frameworks, Libraries, and Embedded Content, add SystemConfiguration.framework, GLKit.framework and VideoToolbox.framework.
  • Add -lstdc++ and -ObjC to the Other Linker Flags.
  • Add @import TwilioVideo; in the source file.

Please note that the TwilioAudioProcessors static framework is not available yet. Using the TwilioAudioProcessors dynamic framework with the TwilioVideo static framework will result in runtime error.

• This version of the Video SDK supports Real-Time Transcriptions in Group rooms. This feature is in Beta.

API Changes

• A new property receiveTranscriptions to enable receiving the transcriptions for the client has been added to the TVIConnectOptions.

let options = ConnectOptions(token: accessToken, block: { (builder) in
    builder.roomName = "test"
    builder.isReceiveTranscriptionsEnabled = true
})

This value can also be retrived using the isReceiveTranscriptionsEnabled getter.

• A new optional method transcriptionReceived(room:transcription:) is added to the RoomDelegate protocol. This callback will be
  invoked when real-time transcription is available in the room. The payload of the callback will contain a JSON desrialized NSDictionary object
  with the transcription data. An example of this dictionary is shown below.

{
    "language_code" = "en-US";
    "partial_results" = 0;
    participant = PA00000000000000000000000000000000;
    "sequence_number" = 2;
    timestamp = "2025-06-23T17:51:47.710028073Z";
    track = MT00000000000000000000000000000000;
    transcription = "This is a test.";
    type = "extension_transcriptions";
}
