can't get extremely simple macOS video player to work...

... following Apple's example. Going off of this tutorial:

https://developer.apple.com/documentation/avfoundation/media_playback_and_selection/creating_a_basic_video_player_macos

I have dragged into the storyboard the AVKit Player View, and here is my ViewController code:

Code Block 
import Cocoa
import AVKit
import AVFoundation
class ViewController: NSViewController {
   
   
  @IBOutlet weak var playerView: AVPlayerView!
   
  override func viewDidLoad() {
    super.viewDidLoad()
     
    guard let url = URL(string: "linkWasHere") else {
        return //could not post actual link due to this forum's security issues, see link above for actual link. ???
    }
     
    let player = AVPlayer(url: url)
    playerView.player = player
  }
}


here is what the console is outputting when I run this, any idea why this no longer works?

AHA! Here is the answer... must use "let fileURL = URL(fileURLWithPath: "myPath")... the below code works for Swift 5.3 and uses a button to allow user to choose internal video. See above SO link for things you need to do to play external video.

Code Block 
import Cocoa
import AVKit
import AVFoundation
class ViewController: NSViewController {
   
   
  @IBOutlet weak var playerView: AVPlayerView!
  @IBOutlet weak var chooseVideoButton: NSButton!
   
  var path: String = ""
   
   
  override func viewDidLoad() {
    super.viewDidLoad()
     
  }
   
  @IBAction func chooseVideoPressed(_ sender: NSButton)
  {
    let dialog = NSOpenPanel();
    dialog.title          = "Choose a video";
    dialog.showsResizeIndicator  = true;
    dialog.showsHiddenFiles    = false;
    dialog.allowsMultipleSelection = false;
    dialog.canChooseDirectories = false;
    if (dialog.runModal() == NSApplication.ModalResponse.OK) {
      let result = dialog.url // Pathname of the file
      if (result != nil) {
        path = result!.path
      }
       
      //let fileURL = URL(string: path)
      let fileURL = URL(fileURLWithPath: path)
      let avAsset = AVURLAsset(url: fileURL, options: nil)
      let playerItem = AVPlayerItem(asset: avAsset)
      let videoPlayer = AVPlayer(playerItem: playerItem)
      playerView.player = videoPlayer
      videoPlayer.play()
       
    } else {
      // User clicked on "Cancel"
      return
    }
  }
   
}
