Not fun!! Why is not working??

Question

In the editor you've been provided with two files buttons.swift that contains some source code for you to use and enums.swift where you will be writing code.

Let's start simple. To a constant named done assign an enum value of type Button with the member Done. This member takes an associated value; assign it the string "Done".

buttons.swift

import Foundation

enum UIBarButtonStyle {
    case Done
    case Plain
    case Bordered
}

class UIBarButtonItem {

    var title: String?
    let style: UIBarButtonStyle
    var target: AnyObject?
    var action: Selector

    init(title: String?, style: UIBarButtonStyle, target: AnyObject?, action: Selector) {
        self.title = title
        self.style = style
        self.target = target
        self.action = action
    }
}

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

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

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

enums.swift

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

Hi Miranda,

I'm sure you already figured that out. Since I started with treehouse I learned one thing - google is your friend! ;-) Here is what I got while googling for your answer: http://cutting.io/posts/the-power-of-swift-enums/

I suppose one of the problems is with the way you declare the enums in enums.swift:

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

I think it should be declared as follows:

enum Button: String {
    case Done
    case Edit
}

Hope it makes sense.
