swift 3 associated enums last quiz error???

Here is my code

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 doneButton = done.button()

What am I doing wrong here??

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 doneButton = done.button()

Instead of 'doneButton' name the constant "button". This should pass the challenge.

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()
