Having problem with code

Hello I've stuck on this task and I can't seem to figure it out.

Thanks for any 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)

    toUIBarButtonItem() -> UIBarButtonItem {
    switch self{
    .Done : UIBarButtonItem(title: Button.Done , style: UIBarButtonStyle.Done, target: nil, action: nil)
    .Edit : UIBarButtonItem(title: Button.Done , style: UIBarButtonStyle.Done, target: nil, action: nil)
    }

    }
}

let doneButton = // ???

Hope this helps:

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

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

}

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

You don't want to delete work from a previous Task. That is, you need to keep

let done = Button.Done("Done")

instead of deleting it.
