My playlistImageView0.image = playlist.icon is throwing an optional is nil fatal error

My build is successful but when my simulator loads the app it fails. I get a "fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)" in my command line and I can't seem to find out what the problem is.

I have all the images in place and the dictionary is all good.

It worked three times before then suddenly it broke

error happens on this line: playlistImageView0.image = playlist.icon

I also see this in my debugger: playlistImageView0=(UIImageView!) nil None

My PlaylistMasterView:

import UIKit

class PlaylistMasterViewController: UIViewController {

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

    override func viewDidLoad() {
        super.viewDidLoad()

        aButton.setTitle("Press me!", forState: .Normal)
        let playlist = Playlist(index: 0)
        playlistImageView0.image = playlist.icon  // The Error happens here
        playlistImageView0.backgroundColor = playlist.backGroundColor
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "showPlaylistDetail" {
            let playlistDetailController = segue.destinationViewController as! PlayListDetailViewControllwerViewController
            playlistDetailController.playlist = Playlist(index: 0)
        }
    }
}

My List Detail:

class PlayListDetailViewControllwerViewController: UIViewController {

    @IBOutlet weak var pressedButtonLabel: UILabel!
    var playlist: Playlist?


    override func viewDidLoad() {
        super.viewDidLoad()

        if playlist != nil {
            pressedButtonLabel.text = playlist!.title
        }

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }  
}
