Can someone clarify here if this challenge is accurate? It seems to be referring to deprecated classes.

Additionally in the error message its asking for a constant name of doneButton which is not mentioned anywhere in the challenge itself.

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, let style, let target, let action):
            return UIBarButtonStyle.done(title: "A Title", style: .plain, target: nil, action: nil)
        case .done(let title, let style, let target, let action):
            return UIBarButtonStyle.plain(title: "A Title", style: .plain, target: nil, action: nil)
        }
    }

}

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

It looks like you're working on task 2, but task 1 asked for a constant named "done" which seems to be missing from this code.

Remember the warning in the instructions that says *"Important: In each task of this code challenge, the code you write should be added to the code from the previous task."

Also, the final step of task two involved creating "a constant named button", which also doesn't appear in this code.
