what's missing?

code looks correct but can't be compiled

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{
BarButton.done: UIBarButtonItem(title: String, style: UIBarButtonStyle.done, target: nil, action: nil)
BarButton.edit.edit: UIBarButtonItem(title: String, style: UIBarButtonStyle.plain, target: nil, action: nil)
   }

    }
}

let doneButton = BarButton.button(BarButton.done(title: "Save"))

let done = BarButton.done(title: "Save")
