AVPlayer 本地视频预览调试错误

Question

我目前正在播放带有捆绑 URL 的本地视频。

private let videoURL = Bundle.main.path(forResource: "video", ofType:"mp4")

这里是 setupPlayer 方法：

player = AVPlayer(url: URL(fileURLWithPath: url))
playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = videoContainerView.layer.bounds
playerLayer.videoGravity = .resize

我可以预览视频和声音，但 Xcode 会产生一些错误。在网上搜索了一些后，我找不到任何关于如何解决它们的信息。

请补充

let playerLayer = AVPlayerLayer(player: player)
view.layer?.addSublayer(playerLayer)

在 iOS 中使用 AVPlayerLayer 的便捷方式，

作为 UIView 的支持层，如以下代码示例所示：

class PlayerView: UIView {
    var player: AVPlayer? {
        get {
            return playerLayer.player
        }
        set {
            playerLayer.player = newValue
        }
    }
    
    var playerLayer: AVPlayerLayer {
        return layer as! AVPlayerLayer
    }
    
    // Override UIView property
    override static var layerClass: AnyClass {
        return AVPlayerLayer.self
    }
}
