iOS Swift 2.0 Enumerations and Optionals Introduction to Enumerations Enum Methods

I have no idea what is the problem with the code I wrote.

I tried to solve but I could not make it

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
    }
}
enums.swift
enum Button {

    case Done(String)
    case Edit(String)

    func toUIBarButtonItem() -> UIBarButtonItem {

      switch self {

        case .Done(let titleValue):
          return UIBarButtonItem(title: titleValue, style: .Done, target: nil, action: nil)
        case .Edit(let titleValue):
          return UIBarButtonItem(title: titleValue, style: .Plain, target: nil, action: nil)

      }

    }
}


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

You've nearly got it. You just need to create an instance of Button called done to pass task 1, and then create a UIBarButtonItem using the toUIBarButtonItem method on done to pass task 2.

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

I hope this helps!

I missed it. Thank you so much.
