解聘后如何停止播放AVPlayerViewController as UIViewRepresentable？

struct PlayerView: UIViewRepresentable {
    func makeUIView(context: Context) -> UIView {
        let playerViewController = AVPlayerViewController()
        // 将playerViewController添加到UIView中
        return playerViewController.view
    }
    
    func updateUIView(_ uiView: UIView, context: Context) {
        // 更新UIView的逻辑
    }
}

func updateUIView(_ uiView: UIView, context: Context) {
    if let playerViewController = uiView as? AVPlayerViewController {
        // 更新AVPlayerViewController的逻辑
        
        // 停止播放
        playerViewController.player?.pause()
    }
}

let playerView = PlayerView()

// 停止播放
playerView.onDismiss()
