Where to start?

I'm not sure where to start with this. I took a shot and i'm falling flat

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

let done = enum Done: String {

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

One place to start if you're having trouble is re-reading the directions. Sometimes there's a ton of information packed in there and it's easy to miss key points. I often find myself re-reading them a couple times before I start on some problems.

Take a look at this problem's first line of directions again:

"In the editor you've been provided with two files: buttons.swift that contains some source code for you to use, and enums.swift where you will be writing code."

After you figure out what needs to change there, here's the way you want to assign the Enum to the constant:

let constant = Enum.Type

(that's not the actual code, you'll need to fill in the correct names for constant, Enum, and Type to fit this problem)
