How to detect Video does not exist state from url in AVPlayer iOS

Question

I am playing videos from urls in AVPlayer. It is working fine. But, Few videos keep loading but not player, I checked them in browser and they are showing Video does not exist.

So, How to detect that video does not exist state and how to show alert for end user understands.

override func viewDidLoad() {
        
        super.viewDidLoad()
        self.setupAVAudioSession()
        
    }

  func playVideo(){
        
        if let str = videoUrl{
            
            if let videoURL:URL = URL(string: str) {
                
                player = AVPlayer(url: videoURL)
                player?.rate = 1 //auto play
                let playerFrame = CGRect(x: 0, y: 0, width: 200, height: 210)
                let playerViewController = AVPlayerViewController()
                playerViewController.delegate = self
                playerViewController.player = player
                playerViewController.view.frame = playerFrame
                playerViewController.showsPlaybackControls = true
                addChild(playerViewController)
                videoPlayerView.addSubview(playerViewController.view)
            }
        }
    }

 func setupAVAudioSession(){
        
        do {
            try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: [])
        }
        catch {
            print("Setting category to AVAudioSessionCategoryPlayback failed.")
        }
    }

func playerViewController(_ playerViewController: AVPlayerViewController, willBeginFullScreenPresentationWithAnimationCoordinator coordinator: UIViewControllerTransitionCoordinator){
}

func playerViewController(_ playerViewController: AVPlayerViewController, willEndFullScreenPresentationWithAnimationCoordinator coordinator: UIViewControllerTransitionCoordinator){
    playerViewController.dismiss(animated: true)
}

Any suggestions?

You can check existence of your video url by sending HEAD request before start playing it e.g.:

var request = URLRequest(url: url)
request.httpMethod = "HEAD"
let session = URLSession(configuration: .default)
let task = session.dataTask(with: request) { data, response, error in
    guard error == nil,
        let r = response as? HTTPURLResponse,
        r.statusCode == 200
    else {
        print("url is not valid")
        return
    }
    
    print("url is valid")
}
task.resume()
