The code I have written gives no error in Playground but is not compiling here. Output window doesn't show any errors

Question

The code I have written is:

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

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

}

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

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 Parameter):
    return UIBarButtonItem(title: Parameter, style: UIBarButtonStyle.Done, target: nil, action: nil)
    case .Edit(let Name):
    return UIBarButtonItem(title: Name, style: UIBarButtonStyle.Plain, target: nil, action: nil)
    }
    }
}

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

You may not have posted all your code, but Task 1 was to create a done constant:

let done = Button.Done("Done")

So without it it's unlikely the editor would let you go on to Task 2. Since you have Task 2 work, you probably just didn't include it here. But when I add that one missing line to your code the editor accepted it. So you are very close!
