User Profile

Due to legal restrictions I need to prevent my app's users from skipping and fast-forwarding the content that is played by AVPlayerViewController. I use playerViewController(:willResumePlaybackAfterUserNavigatedFrom:to:) and playerViewController(:timeToSeekAfterUserNavigatedFrom:to:) delegate methods to control the skipping behaviour. However, those delegate methods are only triggered for skip +/- 10, but not for fast-forwarding/rewinding.  Is there a way to prevent fast-forwarding in addition to skipping in AVPlayerViewController? Here is an example of the code I use: class ViewController: UIViewController {   override func viewDidAppear(_ animated: Bool) {     super.viewDidAppear(animated)     setUpPlayerViewController()   }   private func setUpPlayerViewController() {     let playerViewController = AVPlayerViewController()     playerViewController.delegate = self guard let url = URL(string: "https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_ts/master.m3u8") else {       debugPrint("URL is not found")       return     }     let playerItem = AVPlayerItem(url: url)     let player = AVPlayer(playerItem: playerItem)     playerViewController.player = player     present(playerViewController, animated: true) {       playerViewController.player?.play()     }   } } extension ViewController: AVPlayerViewControllerDelegate {   public func playerViewController(_ playerViewController: AVPlayerViewController, willResumePlaybackAfterUserNavigatedFrom oldTime: CMTime, to targetTime: CMTime) { // Triggered on skip +/- 10, but not on fast-forwarding/rewinding     print("playerViewController(_:willResumePlaybackAfterUserNavigatedFrom:to:)")   }   public func playerViewController(_ playerViewController: AVPlayerViewController, timeToSeekAfterUserNavigatedFrom oldTime: CMTime, to targetTime: CMTime) -> CMTime {     // Triggered on skip +/- 10, but not on fast-forwarding/rewinding     print("playerViewController(_:timeToSeekAfterUserNavigatedFrom:to:)")     return targetTime   } }
