the error message as below: swift_lint.swift:53:57: error: type 'UIBarButtonItem' has no member 'done' return UIBarButtonItem(title: title, style: UIBarButtonItem.done, target: nil, action: nil) ^~~~~~~~~~~~~~~ ~~~~ swift_lint.swift:55:57: error: type 'UIBarButtonItem' has no member 'plain' return UIBarButtonItem(title: title, style: UIBarButtonItem.plain, target: nil, action: nil) ^~~~~~~~~~~~~~~ ~~~~~
does that mean I need import any framework first?
// 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: UIBarButtonItem.done, target: nil, action: nil)
case .edit(let title ):
return UIBarButtonItem(title: title, style: UIBarButtonItem.plain, target: nil, action: nil)
}
}
}
let done = BarButton.done(title: "Save")
let button = done.button()

Treehouse Moderator 145,860 PointsHey there,
You're on the right track, but .done
and .plain
are members of BarButton
not UIBarButtonItem
. So, it's really a simple fix: Just delete UIBarButtonItem
and leave just the member. Because you are in the Enum, you just need .done
and .plain
.
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)
Keep coding! :)
