10,476 PointsThis one was really tough needed a little refresher. Model it like this and it should be good.
enum Button {
case Done(String)
case Edit(String)
func toUIBarButtonItem() -> UIBarButtonItem {
switch self {
case .Done(let title): return UIBarButtonItem(title: title, style: UIBarButtonStyle.Done, target: nil, action: nil)
case .Edit(let title): return UIBarButtonItem(title: title, style: UIBarButtonStyle.Plain, target: nil, action: nil)
}
}
}
let done = Button.Done("Done")
let doneButton = done.toUIBarButtonItem()

6,037 PointsI added in the (let title) as you suggested (both places), but I still the compile error " enums may not contain stored properties" -referring to the following line of code: let done = Button.Done("Done")
