Simple question I can\'t seem to find an answer to for some reason.

How do you loop AVPlayer in Swift?

numberOfLoops = -1 only works for AVAudioPlayer

I've managed to create a seamless video looping for OSX in swift 3. It should work on iOS and with little modification on swift 2 as well.

var player : AVQueuePlayer!

// Looping video initial call
internal func selectVideoWithLoop(url : URL)
{
    let asset = AVAsset(url: url)
    player.pause()
    let playerItem1 = AVPlayerItem(asset: asset)
    let playerItem2 = AVPlayerItem(asset: asset)
    player.removeAllItems()
    player.replaceCurrentItem(with: playerItem1)
    player.insert(playerItem2, after: playerItem1)
    player.actionAtItemEnd = AVPlayerActionAtItemEnd.advance
    player.play()

    let selector = #selector(ViewController.playerItemDidReachEnd(notification:))
    let name = NSNotification.Name.AVPlayerItemDidPlayToEndTime
    // removing old observer and adding it again for sequential calls. 
    // Might not be necessary, but I like to unregister old notifications.
    NotificationCenter.default.removeObserver(self, name: name, object: nil)
    NotificationCenter.default.addObserver(self, selector: selector, name: name, object: nil)
}

// Loop video with threadmill pattern
// Called by NotificationCenter, don't call directly
func playerItemDidReachEnd(notification: Notification)
{
    let item = player.currentItem!
    player.remove(item)
    item.seek(to: kCMTimeZero)
    player.insert(item, after: nil)
}

When you want to change the video, just call selectVideoWithLoop with a different url again.
