// 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)

The correct is below
let done = BarButton.done(title : "Save")

Courses Plus Student 6,898 PointsHi Jeff, thanks for the reply. Tried "Save". Still not working. " Bummer! Make sure you assign the results of the expression to a constant named doneButton"

23,970 PointsAhh I see your error, your just need let button not doneButton
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()
