11,197 PointsHi there. Can I get some help?
It's saying i didnt have a default case even though i used an enum. Also I assigned done.button() to the constant doneButton yet it's saying it hasnt been done. What am I doing wrong? Also for the enum i did this " default: return UIBarButtonItem(title: "edit", style: .plain, target: nil, action: nil) } " to get rid of the error code but shouldnt it be automatic?
// 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(title: "done"): return UIBarButtonItem(title: "done", style: .done, target: nil, action: nil)
case .edit(title: "edit"): return UIBarButtonItem(title: "edit", style: .plain, target: nil, action: nil)
}
}
}
let done = BarButton.done(title: "Save")
let doneButton = done.button()

Everything looks right except the cases of your switch--you need to fix that. The compiler is asking for a default clause because it think that you didn't include all the cases in self--and you didn't.
.done isn't the same as .done(title: "done") .edit isn't the same as .edit(title: "edit")
The compilers believes that you weren't exhaustive because you left out a couple of cases.
