iOS Swift 2.0 Enumerations and Optionals Introduction to Enumerations Enum Methods

Enumeration code challenge

I was trying to Implement the Enum. Its not very clear for me that when we are assigning the associative value to a constant or a variable (eg: case .Mark(let Mark1, let Mark2, let Mark3)) and my code is not working as well. Really appreciate for the help

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("Done"):
            let buttonDone = UIBarButtonItem(title: "Done", style: UIBarButtonStyle.Done, target: nil, action: nil)
            return buttonDone
        case .Edit("Edit"):
            let buttonEdit = UIBarButtonItem(title: "Edit", style: UIBarButtonStyle.Plain, target: nil, action: nil)

            return buttonEdit

        default:

           let defaultButton = UIBarButtonItem(title: "default", style: UIBarButtonStyle.Bordered , target: nil, action: nil)

            return defaultButton
        }


          }
}

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

Your last constant must be named doneButton and not doneButtonFinal
