Question is not clear

I'm not sure if the class is already created for us or not. The question is blurry. I have done everything from scratch but it still doesn't compile. Works well on Xcode. Here is what I compiled:

enum UIBarButtonStyle { case done case plain }

class UIBarButtonItem { var title: String = "A Title" var style: UIBarButtonStyle = .plain var target: String? = nil var action: String? = nil

init (title: String, style: UIBarButtonStyle, target: String?, action: String?) {
    self.title = title
    self.style = style
    self.target = target
    self.action = action
}

}

When I delete the enum and the class, it still doesn't compile. What am I missing?

buttons.swift 
// Example of UIBarButtonItem instance
// let someButton = UIBarButtonItem(title: "A Title", style: .plain, target: nil, action: nil)



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

    func button () -> UIBarButtonItem {
        switch self {
        case .done(let title1): return UIBarButtonItem(title: title1, style: UIBarButtonStyle.done, target: nil, action: nil)
        case .edit(let title2): return UIBarButtonItem(title: title2, style: UIBarButtonStyle.plain, target: nil, action: nil)
        }
    }
}
let done = BarButton.done(title: "Save")
let button = done.button()
