複数のAVPlayerが起動してしまう問題を解決

AVPlayerを終了する時にplayer.replaceCurrentItem(with: nil)を設定する

import UIKit
import AVKit

class PlayerLayerVC: UIViewController {

    var playerLayer = AVPlayerLayer()
    var player : AVPlayer! = AVPlayer()

    override func viewDidDisappear(_ animated: Bool) {
        super.viewDidDisappear(animated)
        
        player.replaceCurrentItem(with: nil)
    }
}
