Enumerations and Optionals in Swift 3: Enum Methods

In challenge 2 of Enum Methods my submitted code gets the message Make sure you assign the results of the expression to a constant named doneButton

I have a constant named doneButton and the code is returning no errors so I don' know how to solve it.

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()

Nevermind, the challenge has been fixed now and the instructions have changed doneButton to button

I can't pass this challenge either, the error states that I need to assign the code to a constant named "doneButton", but the challenge wants me to pass it to a let called "button".

Both of which won't work.

Having the same issue. Using done or doneButton will not work
