iOS Enumerations and Optionals in Swift Introduction to Enumerations Enum Methods

My code is giving this error -> Make sure you assign the results of the expression to a constant named doneButton

Next, add a method to the enum named button that returns an instance of the class UIBarButtonItem configured properly. An example of how to create an instance for this task is shown in the comments below. Use the same initializer. In the method, using the associated values as titles for the button, return a button with style UIBarButtonStyle.done for the done member of the BarButton enum.

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

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

      func toUIBarButtonItem() -> UIBarButtonItem {
      switch self {
      case .done("done"): return UIBarButtonItem(title: "done", style: .done, target: nil, action: nil)

      case .edit("edit"): return UIBarButtonItem(title: "edit", style: .plain, target: nil, action: nil)
    }
  }
}

let doneButton = button.done("done")
let doneButton = done.toUIBarButtonItem()

Any luck with this? I'm having the same issue. In the description for the task, it does not say anything about assigning a constant to doneButton.
