Oleh Kim, your answer is correct, just please post it under "Add an Answer" rather than "Comments". Copy-Paste of Oleh Kim's answer:

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 button = done.button()
