iOS Enumerations and Optionals in Swift Introduction to Enumerations Enum Methods

"Make sure you assign the results of the expression to a constant named doneButton" - I have done that. Still a no go.

Putting this into an Xcode playground produces no errors, I have a constant named doneButton, yet it still says incorrect. I have even compared to other answers and they have the same code I do. Not sure what I am missing here.

// 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()

The code challenges are picky with names.

assign it to a constant named button.

Your constant is named doneButton. Just change the name and it works no problems
