AVPlayer在大屏iPhone上无法占满视图宽度的问题求助

大家好，我碰到一个棘手的问题：在大屏iPhone（比如模拟器里的iPhone 16 Plus）上，我的AVPlayer播放视频时没法按预期占满整个视图宽度，但在iPhone 15 Pro上运行完全正常。我尝试了各种方法来修复，比如给视频设置约束，但都没起作用。下面是我的代码和相关截图，提前感谢大家的帮助！

@IBOutlet weak var cover: UIView!
private var playerLayer: AVPlayerLayer?

private func setupVideoCover() {
    player = AVPlayer(url: videoURL)
    player?.isMuted = true
    player?.actionAtItemEnd = .none
 
    playerLayer = AVPlayerLayer(player: player)
    
    if let playerLayer = playerLayer {
        cover.layer.sublayers?.forEach { $0.removeFromSuperlayer() }
        cover.layer.addSublayer(playerLayer)
    }

    NotificationCenter.default.addObserver(
        self,
        selector: #selector(restartVideoFromBeginning),
        name: .AVPlayerItemDidPlayToEndTime,
        object: player?.currentItem
    )
    
    player?.play()
}

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    playerLayer?.videoGravity = .resizeAspectFill
    playerLayer?.frame = cover.bounds.centered(in: cover.bounds)
}

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    setupVideoCover()
}
