This challenge specifically tells you to use UIBarButtonStyle but the compiler says its an unresolved identifier.

Question

It works in Xcode if you use UIBarButtonItemStyle.

Is this just a typo in the question?

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

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

I believe you are confused by the directions; the style I just plain for both

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

    func button() -> UIBarButtonItem{
        switch self {
        case .done(let title):
            return UIBarButtonItem(title: title, style: .plain, 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()
