39,611 PointsHey Sayuri,
Let me see if I can help on this one. First, the challenge asks you to create a method named button, and you have named yours BarButtonItem. So let’s first create the method stubbing our enum, like so:
func button() -> UIBarButtonItem {
}
For the next part, we need to create a switch statement on our two cases, done and edit. Since these are inside our enum, we need to switch on self. This will look like this:
func button() -> UIBarButtonItem {
switch self {
case .done:
return UIBarButtonItem(title: “Done”, style: .done, target: nil, action: nil)
case .edit:
return UIBarButtonItem(title: “Edit”, style: .plain, target: nil, action: nil)
}
}
See that in our switch statement, we just use the associated values(.done, .edit) so we don’t have to worry about the (title: String) bit. Now that we have our method, we just need to call it on our done constant and store that value in a new constant called button, like so:
let done = BarButton.done(title: “Save”) //this was from task 1
let button = done.button()
This should pass the challenge, once you delete the switch statement you declared outside the enum as well. Hope this helps you out!
