I\'m trying to duplicate this https://jmacmullin.wordpress.com/2010/11/03/adding-meta-data-to-video-in-ios/ in swift.

Here is a video of Jake\'s code in action...

So I got this to work, but ended up ditch MPMovieController opting for AVPlayer. Here is my code, and the link to another post that helped me get it functional.

Timed Metadata with AVPlayer

import UIKit

import MediaPlayer
import AVFoundation

var youtubeRequest: NSURLRequest! = nil
var player : AVPlayer? = nil

var url:NSString!


class ViewController: UIViewController {


var moviePlayer: MPMoviePlayerController?
var movieItem: AVPlayerItem!
var Player: AVPlayer!

var playerLayer : AVPlayerLayer? = nil
var asset : AVAsset? = nil
var playerItem: AVPlayerItem!

var youtubeRequest: NSURLRequest! = nil

@IBOutlet var playButtonOutlet: UIBarButtonItem!

@IBAction func playButtonAction(sender: AnyObject) {player?.play()
    playButtonOutlet.enabled = false

}

@IBOutlet var videoView: UIView!
@IBAction func loadURL(sender: AnyObject) {player?.pause()
    playButtonOutlet.enabled = true
}
@IBOutlet var urlButton: UIButton!
override func viewDidLoad() {

    super.viewDidLoad()



    // Do any additional setup after loading the view, typically from a nib.

    urlButton.enabled = false

    let videoURL = NSURL(string: "http://path/to/video.m3u8")
    playButtonOutlet.enabled = false

    movieItem = AVPlayerItem(URL: NSURL(string: "http://path/to/video.m3u8"))
    movieItem.addObserver(self, forKeyPath: "timedMetadata", options: nil, context: nil)
    Player = AVPlayer(playerItem: movieItem)

    var metaArray: Array = [moviePlayer?.timedMetadata]







    asset = AVAsset.assetWithURL(videoURL) as? AVAsset
    playerItem = AVPlayerItem(asset: asset)
    playerItem = AVPlayerItem(URL: NSURL(string: "http://path/to/video.m3u8"))
    playerItem.addObserver(self, forKeyPath: "timedMetadata", options: nil, context: nil)
    playerItem.addObserver(self, forKeyPath: "presentationSize", options: nil, context: nil)
    player = AVPlayer(playerItem: playerItem)



    playerLayer = AVPlayerLayer(player: player)
    playerLayer!.frame = videoView.bounds

    videoView.layer.addSublayer(self.playerLayer)

    player!.play()

    NSNotificationCenter.defaultCenter().addObserver(

        self,

        selector: "rotated",

        name: UIDeviceOrientationDidChangeNotification,

        object: nil)


}

    override func observeValueForKeyPath(keyPath: String, ofObject object: AnyObject, change: [NSObject : AnyObject], context: UnsafeMutablePointer) -> Void {

        if keyPath != "timedMetadata" { return }

        var data: AVPlayerItem = object as AVPlayerItem

        var urlError = false

        for item in data.timedMetadata as [AVMetadataItem] {

            println(item.stringValue)
            var metaArray: Array = [playerItem?.timedMetadata]
            println("Total objects in array \(metaArray[0])")


            var data = item.stringValue

          url = NSString(string: data) as NSString!



            if url != nil {

             urlButton.enabled = true

                println("The url is \(url)")




            } else {

                urlError = true

            }


            var urlRedirect = NSURL(fileURLWithPath: "\(url)")


            println("The url is \(urlRedirect)")

        }


    }

override func didReceiveMemoryWarning() {

    super.didReceiveMemoryWarning()

    // Dispose of any resources that can be recreated.

}

func rotated()
{
    if(UIDeviceOrientationIsLandscape(UIDevice.currentDevice().orientation))
    {
     self.navigationController?.navigationBarHidden = true
        playerLayer?.frame = CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)
        playerLayer?.frame = CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)

        println("landscape")
    }

    if(UIDeviceOrientationIsPortrait(UIDevice.currentDevice().orientation))
    {
        self.navigationController?.navigationBarHidden = false
        playerLayer!.frame = videoView.bounds

        println("portraight")
    }

 }
