What's the solution to this challenge?

Code attached. Could someone explain to me what am I doing wrong?

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 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

//

Look at the very last line of code :) Happy Coding

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

    func button() -> UIBarButtonItem{
        switch self {
        case .done(let title):
            return UIBarButtonItem(title: title, style: .plain, 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()
