iOS Build a Playlist Browser with Swift Working With Multiple View Controllers A Recap with UIButton

Setting a title quiz - bug?

This seems trivial and obvious so I'm thinking it's a bug in the quiz. It's the same exercise as presented in the PlaylistMasterViewController @IBOutlet, no?

ViewController.swift 
class ViewController: UIViewController {

    @IBOutlet weak var timerButton: UIButton!
    var redColor: UIColor = UIColor.redColor()

    override func viewDidLoad() {
        super.viewDidLoad()
        timerButton.setTitle("Start", forState: . Normal)

    }
}

Forgot to mention that I get the following error:

"You need to use the setTitle method on timerButton."

Additionally, if I remove the forState declaration, I get an error stating that I need to specify that. Beyond that, if I specify some other title besides, "Start", I get an error saying that I need to set the title to the correct string. That all leads me to believe that what I have above is correct and that the treeshouse quiz app is a little drunk.

Vince,

I just completed the challenge with this:

    class ViewController: UIViewController {

        @IBOutlet weak var timerButton: UIButton!
        var redColor: UIColor = UIColor.redColor()

        override func viewDidLoad() {
            super.viewDidLoad()

            //Add your code below
            timerButton.setTitle("Start", forState: .Normal)
        }
    }

Looks like you have a space between your enum case for the second argument to the setTitle:forState: method. You have . Normal. Just remove the space and .Normal should work for you.

I tried to get some help with the documentation, but cannot figure out where is this piece of code... Can you help me to help myself? :) Where can I find this in the documentation?
