Not sure what I am doing wrong here. Preview doesn't show any errors.
// 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(barButton: BarButton) -> UIBarButtonItem {
switch barButton {
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 = BarButton.button(done)

Courses Plus Student 27,294 PointsWow I am silly... I needed to refer to the enum it"self" while switching within the method, instead of trying to pass an instance...
// 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()
