Swift play video in TableviewCell URL from firebase - ios

Question

I have a tableview which can display images or videos.
When it comes to images I get no problems.
But when it comes to video I'm getting an error on the console which I don't understand.
The error is : "Task .<2> finished with error - code: -999"
From the research I've made it should be exit before execution.
But I really don't understand what it means.
Here's my code for the tableView Cell:
var post: Post? {
didSet {
updateView()
}
}
func updateView() {
captionLbl.text = post?.caption
usernameLbl.text = "Test"
if (post?.isVideo)! {
if let videoThumbUrlString = post?.videoThumbUrl {
let videoThumbUrl = URL(string: videoThumbUrlString)
postImgView.sd_setImage(with: videoThumbUrl)
}
}
if !(post?.isVideo)! {
if let photoUrlString = post?.photoUrl {
let photoUrl = URL(string: photoUrlString)
postImgView.sd_setImage(with: photoUrl)
}
}
}
func createPlayer() {
if (post?.isVideo)! {
if let videoUrlString = post?.videoUrl, let url = URL(string: videoUrlString) {
player = AVPlayer(url: url)
playerLayer = AVPlayerLayer(player: player)
playerLayer?.frame = self.postImgView.bounds
playerLayer?.videoGravity = AVLayerVideoGravity.resizeAspectFill
self.postImgView.layer.addSublayer(playerLayer!)
player?.play()
activityIndicatorView.startAnimating()
playBtn.isHidden = true
}
}
}
#IBAction func playBtnPressed(_ sender: Any) {
createPlayer()
}
override func prepareForReuse() {
super.prepareForReuse()
playerLayer?.removeFromSuperlayer()
player?.pause()
activityIndicatorView.stopAnimating()
}
When i tap on playButton the video plays but i get the error I've mentioned before.
I'm not sure if is connected but also the activity indicator never stops running.
Hope somebody can help!
Thank you.
---------------------UPDATE
The full console log message is:
"
2017-10-30 14:10:00.996661+0100 PhotoApp[92272:543501] Task .<2> finished with error - code: -999

Well, error does not show something. But try next change:
if let videoUrlString = post?.videoUrl, let url = URL(string: videoUrlString) {
let asset = AVURLAsset(url: url) // < --
player = AVPlayer(playerItem: AVPlayerItem(asset: asset)) // < --
playerLayer = AVPlayerLayer(player: player)
playerLayer?.frame = self.postImgView.bounds
playerLayer?.videoGravity = AVLayerVideoGravity.resizeAspectFill
self.postImgView.layer.addSublayer(playerLayer!)
player?.play()
activityIndicatorView.startAnimating()
playBtn.isHidden = true
}
