I don't understand how to do this.

I have no idea what I'm doing wrong. Here's my code:

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

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

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

The complier doesn't display anything but the error message says that there's a compiling error...
