AVPlayer layer inside a view does not resize when UIView frame changes

Question

I have a UIView which contains an AVPlayer to show a video. When changing orientation, I need to change the size and location of the video.

Converting @Suran's solution to Swift:

First, create a class inheriting UIView where you override only 1 variable:

import UIKit
import AVFoundation

class AVPlayerView: UIView {
    override class var layerClass: AnyClass {
        return AVPlayerLayer.self
    }
}

Then add a simple UIView using the interface builder and change its class to the one you just created: AVPlayerView

Then, make an outlet for that view. Call it avPlayerView

@IBOutlet weak var avPlayerView: AVPlayerView!

Now, you can use that view inside your viewcontroller and access its avlayer like this:

let avPlayer = AVPlayer(url: video)
let castedLayer = avPlayerView.layer as! AVPlayerLayer
castedLayer.player = avPlayer
avPlayer.play()

The layer will now follow the constraints just like a regular layer would do. No need to manually change bounds or sizes.
