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

    func button() -> UIBarButtonItem {
        switch self {
        case .done : return UIBarButtonItem(title: "Plain", style: .done, target: nil, action: nil)
        case .edit : return UIBarButtonItem(title: "Edit", style: .plain, target: nil, action: nil)
        }
    }
}

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

You have wrong return declaration.
