Why is `let done = Button.Done("Done")` incorrect?

let done = Button.Done("Done")

Hi Amitai,

Hmm... that's odd because in my case it accepted the code for part 1.

Here is what I entered.

let done = Button.Done("Done")

For the second part, I created a switch statement inside the function and ended up with something like this.

enum Button {
    case Done(String)
    case Edit(String)

    func toUIBarButtonItem() -> UIBarButtonItem {
        switch self {
        case Done:
            let buttonItem = UIBarButtonItem(title: "Done", style: UIBarButtonStyle.Done, target: nil, action: nil)
            return buttonItem
        case Edit:
            let buttonItem = UIBarButtonItem(title: "Edit", style: UIBarButtonStyle.Plain, target: nil, action: nil)
            return buttonItem
        }
    }
}

let done = Button.Done("Done")
let doneButton = done.toUIBarButtonItem()

Whenever I have trouble with the code challenges, I am open up a new Playground in Xcode and play around with what was provided until I get comfortable with it. I usually solve all challenges first in the Playground before going back to the code challenge. I find it a fantastic tool to help me learn.

I hope that helps,

Mike

PS: Thanks to the awesome resources on Team Treehouse, I just launched my first app. :-)

Glad to know it's a bug over here. This is not the only code challenge where I've gotten inexplicable errors - in fact, every submission has been marked error since a few days ago.
