AVQueuePlayer playback without gap and freeze

Question

I use AVQueuePlayer to play a sequence of movies which are loaded from URLs.
I tried to initialize player instance with array of all AVPlayerItems

Answer 1

in Swift 2, working here:

func load() {
     let player = AVQueuePlayer()
     for url in urls {
        makeItem(url)
    }
}

func makeItem(url: String) {
    let avAsset = AVURLAsset(URL: NSURL(string: url)!)

    avAsset.loadValuesAsynchronouslyForKeys(["playable", "tracks", "duration"], completionHandler: {
        dispatch_async(dispatch_get_main_queue(), {
            self.enqueue(avAsset: avAsset)
        })
    })
}

func enqueue(avAsset: AVURLAsset) {
    let item = AVPlayerItem(asset: avAsset)
    self.player.insertItem(item, afterItem: nil)
}
