How to add cornerRadius to AVPlayerViewController in Swift?

Question

i'm working on video player app that written in Swift.

my problem is i should make AVPlayerViewController corners curve. but i want to use just AVPlayerViewController not any other classes.

what i did now:

fileprivate func setupPlayer() {
    let player = AVPlayer(url: videoURL)
    let playerViewController = AVPlayerViewController()
    playerViewController.view.frame = CGRect.init(x: xPosition,
                                                  y: yPosition,
                                                  width: 200,
                                                  height: 100)
    playerViewController.player = player
    self.addChild(playerViewController)
    self.view.addSubview(playerViewController.view)
    playerViewController.didMove(toParent: self)
    playerViewController.videoGravity = AVLayerVideoGravity.init(rawValue: "")
    playerViewController.view.backgroundColor = UIColor(displayP3Red: 0/255, green: 0/255, blue: 0/255, alpha: 0)
    playerViewController.view.layer.cornerRadius = 20
    playerViewController.contentOverlayView?.isHidden = true
    playerViewController.contentOverlayView?.alpha = 0
}

Problem:

what i already have is:

Answer 1

The AVPlayerViewController adds a sub layer to your view. When you set the playerViewController.view.layer.cornerRadius property it only affects it and not its children.

To fix it you must clip the subviews (or here the sublayer) by using the masksToBounds layer property.

playerViewController.view.layer.masksToBounds = true
