Assigned value to doneButton but still says I need to assign it to doneButton

It says to assign the value to doneButton and I've changed it. What's wrong?

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

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