Cant replay video after finish playing - ios

Question

I use following code to reveal two different video-sources as background. The "selectVideo" (SegmentedControl) is used to select video. The problem is down below.
#IBAction func selectVideo(sender: AnyObject) {
if self.Controller.selectedIndex == 1 {
self.videoBackgroundCustomer()
}
if self.Controller.selectedIndex == 0 {
self.videoBackgroundDriver()
}
}
func videoBackgroundDriver() {
//Load video background.
let videoURL: NSURL = NSBundle.mainBundle().URLForResource("background_video_2", withExtension: "mp4")!
player = AVPlayer(URL: videoURL)
videoBackground()
}
//Video background customer
func videoBackgroundCustomer() {
//Load video background.
let videoURL: NSURL = NSBundle.mainBundle().URLForResource("background_video_1", withExtension: "mp4")!
player = AVPlayer(URL: videoURL)
videoBackground()
}
//Vieobackground-code part 2, provides with less code.
func videoBackground() {
player?.actionAtItemEnd = .None
player?.muted = true
let playerLayer = AVPlayerLayer(player: player)
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
playerLayer.zPosition = -1
playerLayer.frame = view.frame
view.layer.addSublayer(playerLayer)
player?.play()
//call loop video
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(LoginViewController.loopVideo), name: AVPlayerItemDidPlayToEndTimeNotification, object: player!.currentItem)
}
//Loop video
func loopVideo() {
player?.seekToTime(kCMTimeZero)
player?.play()
}
Problem: The video restarts when the last video should have ended. And not when the most recent video ends.
How do I make it repeat playing after the last playing video finished? Thanks

After investigation of the problem firstly take a look at documentation and return values of the method.
- (void)seekToTime:(CMTime)time;
Method that you are using return void and could not be compared to the CMTime
For solving of you're problem try this solution:
First you need to subscribe you're class to the notification that will indicate that video is ended.
NSNotificationCenter.defaultCenter().addObserver(self,selector: "itemDidReachEnd:",
name: AVPlayerItemDidPlayToEndTimeNotification,
object: player.currentItem)
And than define method to handle this notification.
func itemDidReachEnd(notification: NSNotification) {
player.seekToTime(kCMTimeZero)
player.play()
}
In this case you are tracking when video ends and you start it again.
