I get the error "PlaylistDetailViewController .Type does not have a member named segueLabelText

I have been checking this so long, I can't seem to find the error? I tried editing segueLabelText to buttonPressLabel.text but that didn't work for me either.. Here is my code

import UIKit

class PlaylistMasterViewController: UIViewController {

@IBOutlet weak var aButton: UIButton!


override func viewDidLoad() {
    super.viewDidLoad()


    aButton.setTitle("Press Me!", forState: .Normal)
}

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
        PlaylistDetailViewController.segueLabelText = "Yay! You pressed the button!"

    }
}

}

class PlaylistDetailViewController: UIViewController {

@IBOutlet weak var buttonPressLabel: UILabel!
var segueLabelText: String = ""

override func viewDidLoad() {
    super.viewDidLoad()


buttonPressLabel.text = segueLabelText

}

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

}

It's a very simple and annoying error but this is your code:

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

    }
}

In the line where you try and set segueLabelText you are using PlaylistDetailViewController the class name and not playlistDetailViewController the instance of PlaylistDetailViewController

I hope this isn't confusing but this is what is should be:

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

    }
}

Thank you so much! Luckily I found the error myself the day after, probably just needed to take me eyes from it a bit.

Anyways thanks a lot!
