func button() -> UIBarButtonItem {
switch self {
case .done(title: let title): return UIBarButtonItem(title: title, style: .done, target: nil, action: nil)
case .edit(title: let title): return UIBarButtonItem(title: title, style: .plain, target: nil, action: nil)
}
}
And don't forget to call it on the done
constant:
let button = done.button()
