iOS Swift 2.0 Enumerations and Optionals Introduction to Enumerations Enum Methods

I don't get the point of the questions, and my code won't work

I think the challenge is simple, but I still don't get the point what the question is. so I just wrote the code as the picture I have attached. and the code won't work. please somebody help me. I love this course :-)

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
    }

}

// write code here and I dont really know the question
//Let's start simple. To a constant named done assign an enum value of type Button with the member Done. This member takes an associated value; assign it the string "Done".

let done = UIBarButtonStyle.Done
enums.swift
enum Button {
    case Done(String)
    case Edit(String)
}
