How can I add PiP support to my iOS app?

To add Picture-in-Picture (PiP) support to your iOS app, you can utilize the AVKit framework, specifically the AVPlayerViewController. While the context provided does not directly address PiP, it does mention the use of AVPlayerViewController for video playback, which is a key component in implementing PiP functionality.

Here's a general approach to adding PiP support:

1. Use AVPlayerViewController: This controller provides a built-in PiP button when the video is playing. You can present your video content using AVPlayerViewController.

2. Enable PiP: Ensure that your app's Info.plist file includes the UIBackgroundModes key with the audio value to allow background audio playback, which is often necessary for PiP.

3. Implement Delegate Methods: Use the AVPictureInPictureControllerDelegate to manage the PiP lifecycle and handle events such as starting and stopping PiP.

4. Start PiP Programmatically: You can also start PiP programmatically by creating an instance of AVPictureInPictureController with your AVPlayerLayer and calling the startPictureInPicture() method.

For more detailed guidance, you might want to refer to Apple's documentation on AVKit and Picture-in-Picture.
