• The Privacy Manifest is updated since the SDK does not collect API usage or call quality data for tracking purposes according to Apple's documentation.

Known Issues

• Audio playback fails in some cases when running a simulator on a Mac Mini. #182
• Unpublishing and republishing a LocalAudioTrack or LocalVideoTrack might not be seen by Participants. #34

Enhancements

• The SDK now includes the privacy manifest in the XCFramework. The SDK collects analytic data such as WebRTC stats when the insightsEnabled property is enabled in TVIConnectOptions.
  The required reason APIs included in the privacy manifest are for internal usage by WebRTC and are not used directly by the Video SDK.
• The SDK XCFramework is now signed with Twilio's distribution signature.

Bug Fixes

• The following thread performance checker warning has been resolved

  Thread Performance Checker: -[AVCaptureSession startRunning] should be called from background thread. Calling it on the main thread can lead to UI unresponsiveness

Maintenance

• Bitcode is now disabled for all builds due to deprecation by Apple since the release of Xcode 14. See excerpt below from Xcode 14 Release Notes: Deprecations

  Starting with Xcode 14, bitcode is no longer required for watchOS and tvOS applications, and the App Store no longer accepts bitcode submissions from Xcode 14.

  Xcode no longer builds bitcode by default and generates a warning message if a project explicitly enables bitcode: “Building with bitcode is deprecated. Please update your project and/or target settings to disable bitcode.” The capability to build with bitcode will be removed in a future Xcode release. IPAs that contain bitcode will have the bitcode stripped before being submitted to the App Store. Debug symbols can only be downloaded from App Store Connect / TestFlight for existing bitcode submissions and are no longer available for submissions made with Xcode 14. (86118779)

5.3.0

• Programmable Video iOS SDK 5.3.0 [XCFramework] (checksum: 128e56119ce21d799777342eeedead6d73e52ae6d50ed8c57aadc9c353b76473
  ).

Enhancements

• Picture in Picture mode is now supported with the SDK. A new renderer SampleBufferVideoView is added for picture in picture support. In order for picture in picture to work on iOS 15+, your app must have com.apple.developer.avfoundation.multitasking-camera-access entitlement.

The following code, from our Twilio Video iOS App, illustrates implementing picture in picture using SampleBufferVideoView:

class PictureInPictureViewController: UIViewController {

    @IBOutlet weak var videoView: VideoView!

    private var pipController: AVPictureInPictureController!
    private var pipVideoCallViewController: AVPictureInPictureVideoCallViewController!
    
    override func viewDidLoad() {
        let sampleBufferVideoCallView = SampleBufferVideoView()
        sampleBufferVideoCallView.contentMode = .scaleAspectFit
        
        pipVideoCallViewController = AVPictureInPictureVideoCallViewController()
        pipVideoCallViewController.preferredContentSize = CGSize(width: 1080, height: 1920)
        pipVideoCallViewController.view.addSubview(sampleBufferVideoCallView)

        sampleBufferVideoCallView.translatesAutoresizingMaskIntoConstraints = false
        let constraints = [
            sampleBufferVideoCallView.leadingAnchor.constraint(equalTo: pipVideoCallViewController.view.leadingAnchor),
            sampleBufferVideoCallView.trailingAnchor.constraint(equalTo: pipVideoCallViewController.view.trailingAnchor),
            sampleBufferVideoCallView.topAnchor.constraint(equalTo: pipVideoCallViewController.view.topAnchor),
            sampleBufferVideoCallView.bottomAnchor.constraint(equalTo: pipVideoCallViewController.view.bottomAnchor)
        ]
        NSLayoutConstraint.activate(constraints)


        sampleBufferVideoCallView.bounds = pipVideoCallViewController.view.frame

        let pipContentSource = AVPictureInPictureController.ContentSource(
            activeVideoCallSourceView: videoView,
            contentViewController: pipVideoCallViewController
        )
        
        pipController = AVPictureInPictureController(contentSource: pipContentSource)
        pipController.canStartPictureInPictureAutomaticallyFromInline = true
        pipController.delegate = self
    }
}

Please note that the render hints are not supported in picture in picture mode except for the track switch on and off hints when the SampleBufferVideoView renderer is added and removed from the RemoteVideoTrack respectively. As a result when the app is in the background and in picture in picture mode, the displayed RemoteVideoTrack will still be active (e.g Dominant Speaker track), consuming bandwidth, and it will have the default spatial dimension determined by the media server.
