2,395 PointsQuestion need some help with
Hey guys, I don't understand why it is done.button and not button.done in the instance. Shouldn't we reference from the method first? I don't understand, any help would be great!
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()
//WHY is it done.button instead of button.done. shouldnt we refrence from button.done

I think that the reason for this is that the done case in the BarButton Enum contains the UIBarButtonItem. So in order to return a doneButton you must first access the .done type.
