iOS Enumerations and Optionals in Swift Introduction to Enumerations Enum Methods

Enumerations and Optionals Swift 3.0 Enumeration Code Challenge Task 2 of 2

I have been on this prompt for hours. First off, no "initialization" example was listed (this being the Swift 3.0 version of the course, maybe they left it out?)

I was only able to pull what the UIBarButtonStyle class was from old posts about the Swift 2.0 version of the problem. Their solutions were not working for this question either.

Please tell me where I am going wrong?

buttons.swift 
enum BarButton {
    case done(title: String)
    case edit(title: String)

    func button() -> UIBarButtonItem {
        switch self {
        case .done(let doneValue):
            return UIBarButtonItem(title: doneValue, style: UIBarButtonStyle.Done, target: nil, action: nil)
        case .edit(let editValue):
            return UIBarButtonItem(title: editValue, style: UIBarButtonStyle.Plain, target: nil, action: nil)
        }
    }
}
let done = BarButton.done(title: "Save")
let button = done.button()

Solved it:

For onlookers, make sure you ignore some of the error messages when debugging. The error messages will tell you to name your constant doneButton 

enum BarButton {
    case done(title: String)
    case edit(title: String)

    func button() -> UIBarButtonItem {
        switch self {
        case .done(let title):
            return UIBarButtonItem(title: title, style: .done, target: nil, action: nil)
        case .edit(let title):
            return UIBarButtonItem(title: title, style: .plain, target: nil, action: nil)
        }
    }
}
let done = BarButton.done(title: "Save")
let button = done.button()
