AVKit – Video clips loop just 2 times - ios

Question

I have got four video clips and I want to play them endlessly. But my AVQueuePlayer() loops all the videos just 2 times and then stops.
How to make them play endlessly?
Here's my code:
import UIKit
import AVKit
class ViewController: UIViewController {
private let player = AVQueuePlayer()
let clips = ["001", "002", "003", "004"]
private var token: NSKeyValueObservation?
var avPlayerView = AVPlayerViewController()
override func viewDidLoad() {
super.viewDidLoad()
self.addAllVideosToPlayer()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(true)
self.addAllVideosToPlayer()
}
func addAllVideosToPlayer() {
avPlayerView.player = player
for clip in clips {
let urlPath = Bundle.main.path(forResource: clip, ofType: "m4v")!
let url = URL(fileURLWithPath: urlPath)
let playerItem = AVPlayerItem(url: url)
player.insert(playerItem, after: player.items().last)
token = player.observe(\.currentItem) { [weak self] player, _ in
if self!.player.items().count == 1 { self?.addAllVideosToPlayer() }
}
avPlayerView.showsPlaybackControls = false
player.volume = 0.0
}
present(avPlayerView, animated: true, completion: { self.player.play() })
}
}

Answer 1

I solved my problem. I deleted viewDidLoad() method and placed present() function into viewDidAppear().
Here's how it looks like:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(true)
self.addAllVideosToPlayer()
present(avPlayerView, animated: true, completion: { self.player.play() })
}
