Can't figure out Enums and Operations Code Challenge

Can't seem to figure out what went wrong. The error tells me that enums can't store values and is referring to the "let done = Button.Done("Done")" line that was already verified as correct in the fist step. Please advise!

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

let done = Button.Done("Done")

Your code is actually correct, but you're missing a close-bracket in enums.swift, so the compiler is trying to include that let done = line as part of the Button enum.
