AVPlayerViewController delegate function not called when user seek

Question

I have been trying to get the notification from Avplayerviewcontroller when user seek. I found a method in AvplayerControllerdelegate which is called when user scrub however that function is not getting called.

class ViewController: UIViewController, AVPlayerViewControllerDelegate {

override func viewDidLoad() {
    super.viewDidLoad()
    let url = URL(string:
        "https://dl.pagal.link/upload_file/367/382/7491/Bollywood%20MP4%20Video%20Songs%202015/Super%20Girl%20From%20China%20-%20Sunny%20Leone%20Mp4/Super%20Girl%20From%20China%20-%20Video%20Song%20-%20Sunny%20Leone%20-%20MP4.mp4")
    let player = AVPlayer(url: url!)
    let playerController = AVPlayerViewController()
    playerController.player = player
    playerController.delegate = self
    self.addChildViewController(playerController)
    self.view.addSubview(playerController.view)
    playerController.view.frame = self.view.frame

    player.play()

}


func playerViewController(_: AVPlayerViewController, timeToSeekAfterUserNavigatedFrom: CMTime, to: CMTime){
    print("Called when scrubb")
}
func playerViewController(_: AVPlayerViewController, willResumePlaybackAfterUserNavigatedFrom: CMTime, to: CMTime){
    print("Called when scrubs")
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


}

Because as apple developer documents said , its just for Apple Tv

On Apple TV, you can implement methods related to playback navigation, interstitial content, and content proposals.

If you create an app for Apple TV and implement AVPlayerViewControllerDelegate you can see use this method but for iphone you can't find this method in AVPlayerViewControllerDelegate
