Twilio Video SDK iOS 4.4.0

This release consumes twilio-video-cpp-6.1.0.

Enhancements

• 100 Participant Group Rooms Pilot Program: A Group Room created with max participants greater than 50 is structured to support a small number of presenters and a large number of viewers. It has the following behavioral differences compared to regular Group Rooms:
  • The RoomDelegate.participantDidConnect() delegate method is invoked when a RemoteParticipant connects to the Room and publishes at least one Track.
  • The RoomDelegate.participantDidDisconnect() delegate method is invoked when a RemoteParticipant disconnects from the Room or unpublishes all of its Tracks.
  • If a RemoteParticipant unpublishes all of its tracks (resulting in the RoomDelegate.participantDidDisconnect() delegate method being invoked) and later republishes a track, a new RemoteParticipant object will be provided in the subsequent RoomDelegate.participantDidConnect() delegate method invocation with the same Participant Sid as before.
  • The maximum number of published Tracks in a Room at the same time cannot exceed 16. Attempts to publish more Tracks will result in a publication failure with ParticipantMaxTracksExceededError unless one or more published Tracks is unpublished.
  • Contact your Twilio Account Executive to enroll in this pilot program.

Bug Fixes

• Fixed a crash when network manager was still invoking onNetworksChanged callback while network monitor was being destroyed.

Known Issues

• The TwilioVideo.xcframework does not currently support the simulator on Apple Silicon arm64 Macs.
• Carthage is not currently a supported distribution mechanism for Twilio Video. Carthage does not currently work with .xcframeworks as documented here. Once Carthage supports binary .xcframeworks, Carthage distribution will be re-added.
• Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. #34
• H.264 video might become corrupted after a network handoff. #147
• iOS devices do not support more than three H.264 encoders. Refer to #17 for suggested work arounds.
• Publishing H.264 video at greater than 1280x720 @ 30fps is not supported. If a failure occurs then no error is raised to the developer. [ISDK-1590]
