1,028 PointsWhat's wrong? I guess that I incorrectly assign a value to a new button constant.
Could you describe me my mistake please?
// 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(title: BarButton) -> UIBarButtonItem {
switch title {
case .done: return UIBarButtonItem(title: BarButton.done, style: UIBarButtonStyle.done, target: nil, action: nil)
case .edit: return UIBarButtonItem(title: BarButton.edit, style: UIBarButtonStyle.plain, target: nil, action: nil)
}
}
}
let save = BarButton.done(title: "Save")
let button = save.button(title: .done)

You were close! Some minor changes:
// 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: .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()
