2,494 Points"An enum named Button" challenge throwing an error
The error I'm receiving says "Make sure you assign the results of the expression to a constant named doneButton". So I did that and I still get the error. Can someone point me in the right direction?
// Example of UIBarButtonItem instance
// let someButton = UIBarButtonItem(title: "A Title", style: .plain, target: nil, action: nil)
import UIBarButtonItem
enum BarButton {
case done(title: String)
case edit(title: String)
}
func button() -> UIBarButtonItem {
switch self {
case .done(let title, let style, let target, let action):
return UIBarButtonStyle(title: String, style: .plain, target: nil, action: nil)
case .edit(let title, let style, let target, let action):
return UIBarButtonStyle(title: String, style: .plain, target: nil, action: nil)
}
}
let doneButton = BarButton.done(title: "A title", style: .done, target: nil, aciton: nil).button()

23,970 PointsIt looks as though you are just stuck on the last part; here is how it should look. Let me know if you have any questions
enum BarButton {
case done(title: String)
case edit(title: String)
func button() -> UIBarButtonItem{
switch self {
case .done(let title):
return UIBarButtonItem(title: title, style: .plain, 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()
