Python Web Development Techdegree Student 6,077 PointsI can't seem to be able to solve step 2 of this code challenge. Sample code would be appreciated?
I'm just confused with this challenge. I've tried several things and it seems I just keep creating additional 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() -> UIBarButtonItem {
switch self {
case BarButton.done(let done): return someButton(title: done, style: UIBarButtonStyle.done, target: nil, action: nil)
case BarButton.edit(let edit): return someButton(title: edit, style: UIBarButtonStyle.plain, target: nil, action: nil)
}
}
}
let done = BarButton.done(title: "Save")
let button = done.button()

Python Web Development Techdegree Student 6,077 PointsThank you. I was able to get it to pass the code challenge. However, in xcode I keep getting an error message - "Use of undeclared type 'UIBarButtonItem".
func button() -> UIBarButtonItem
