Nothing is updating..

when I run my app the labels and the ImageView do not get updated, I'm sure it has to do with the IBOutlets but I cannot find out what's wrong

here is my detailViewController code:

import UIKit

class PlaylistDetailViewController: UIViewController {

    var playlist: Playlist?

    @IBOutlet weak var playListCoverImage: UIImageView!
    @IBOutlet weak var playListDescription: UILabel!
    @IBOutlet weak var playListTitle: UILabel!
    var segueLabelText: String = ""

    override func viewDidLoad() {
        super.viewDidLoad()
        if playlist != nil {
            playListCoverImage.image = playlist!.largeIcon
            playListCoverImage.backgroundColor = playlist!.backgroundColor
            playListTitle.text = playlist!.title
            playListDescription.text = playlist!.description
        }

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

and here's my MasterViewController code also:

import UIKit

class PlaylistMasterViewController: UIViewController {

    @IBOutlet weak var aButton: UIButton!
    @IBOutlet weak var playlistImageView0: UIImageView!
    @IBOutlet var backgroundColor: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()

        aButton.setTitle("Press me!", forState: UIControlState.Normal)
        let playlist = Playlist(index: 0)
        playlistImageView0.image = playlist.icon
        backgroundColor.backgroundColor = playlist.backgroundColor
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }







    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "showPlaylistDetail" {
            let playlistDetailController = segue.destinationViewController as! PlaylistDetailViewController
            playlistDetailController.segueLabelText = "Yay! You pressed the button"
        }
    }
}

I found the mistake, my last line of code in the MasterViewController was missing:

playlistDetailController.playlist = Playlist(index: 0)
