Need help understanding this code challenge.

I can't understand the logic behind this code challenge. Would like if someone shows me the code that will work. Would love if someone explained it. Please 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() -> UIBarButton
}

let done = Button.Done("Done")

Hey Abby,

I struggled with this one too.

Steven gives a pretty thorough explanation in this post, and Nathan gives line-by-line comments in this post.

Go through these as many times as you need... it does become more clear (sort of... lol). Keep Coding! :smiley:
