How to make a video loop in Xcode swift 5? - swift

Question

I am trying to get a video background in my app and I have written the following code. It runs one time and then stops. How do I make the video repeat forever? Thanks in advance.
#IBOutlet weak var videoLayer: UIView!
override func viewDidLoad() {
super.viewDidLoad()
playBackgroundVideo()
}
func playBackgroundVideo(){
guard let path = Bundle.main.path(forResource: "City", ofType: "MOV") else {
return
}
let player = AVPlayer(url: URL(fileURLWithPath: path))
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
playerLayer.videoGravity = .resizeAspectFill
self.videoLayer.layer.addSublayer(playerLayer)
player.play()
}
#objc func playerItemDidReachEnd(notification: Notification) {
let p: AVPlayerItem = notification.object as! AVPlayerItem
p.seek(to: .zero)
}
}

Answer 1

Try adding a notification listener to trigger the playerItemDidReachEnd code.
You do this by involving a NotificationCenter.default.addObserver in your setup.
Did not test your code, but you want a setup like this example:
#IBOutlet weak var videoLayer: UIView!
var player: AVPlayer!
override func viewDidLoad()
{
super.viewDidLoad()
playBackgroundVideo()
}
func playBackgroundVideo()
{
guard let path = Bundle.main.path(forResource: "City", ofType: "MOV") else{ return }
player = AVPlayer(url: URL(fileURLWithPath: path))
let playerLayer = AVPlayerLayer(player: player)
//# add a Listener
NotificationCenter.default.addObserver( self,
selector: #selector(playerItemDidReachEnd),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
object: nil)
playerLayer.frame = self.view.bounds
playerLayer.videoGravity = .resizeAspectFill
self.videoLayer.layer.addSublayer(playerLayer)
player.play()
}
#objc func playerItemDidReachEnd(notification: Notification)
{
player.seek(to: CMTime.zero)
player.play()
}
