花了一些时间仔细看看故事板后，我尝试将填充更改为Aspect fill&适合并解决了问题：）

I have a video view set to full screen. However while playing in the simulator, it is not running full screen.

This issue is only for iPads and not iPhones.

Here is my code:

override func viewDidAppear(_ animated: Bool) {

    super.viewDidAppear(true)

    let bundle: Bundle = Bundle.main
    let videoPlayer: String = bundle.path(forResource: "normalnewer", ofType: "mp4")!
    let movieUrl : NSURL = NSURL.fileURL(withPath: videoPlayer) as NSURL
    //        var fileURL = NSURL(fileURLWithPath: "/Users/Mantas/Desktop/123/123/video-1453562323.mp4.mp4")
    playerView = AVPlayer(url: movieUrl as URL)

    NotificationCenter.default.addObserver(self,selector: #selector(playerItemDidReachEnd),name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,object: self.playerView.currentItem) // Add observer

            var playerLayer=AVPlayerLayer(player: playerView)
//        self.avPlayerLayer.playerLayer = AVLayerVideoGravityResizeAspectFill


    playerLayer.frame = viewVideo.bounds
//        self.playerLayer.frame = self.videoPreviewLayer.bounds

    viewVideo.layer.addSublayer(playerLayer)




    playerView.play()

    UserDefaults.standard.set("normalnewer", forKey: "video")




}

I have tried checking landscape mode in target's general. Gone through the threads below: how to play a video in fullscreen mode using swift ios?

Play video fullscreen in landscape mode, when my entire application is in lock in portrait mode

Setting device orientation in Swift iOS

But these did not resolve my issue. Here is a screenshot.

Can somebody help me resolve this?

After spending some time taking a good look at the Storyboard, I tried changing the fill to Aspect fill & fit and that resolved the problem :)
