I am stuck with the second task of the Enum Methods challenge.

Can anyone post their solution so I can figure out where I messed up? I'm stuck for a few hours now and it's getting really frustrating. Thanks!

Hi Jacob,

If you post the code that you've tried so far, we're able to point you in the right direction - and potentially help you learn more from the Challenge - than if we just give you the answer.

That said, this code will pass the Challenge:

enum Button {
    case Done(String)
    case Edit(String)

  func toUIBarButtonItem() -> UIBarButtonItem {
        switch self {
        case .Done: return UIBarButtonItem(title: "Done", style: UIBarButtonStyle.Done, target: nil, action: nil)
        case .Edit: return UIBarButtonItem(title: "edit", style: UIBarButtonStyle.Plain, target: nil, action: nil)
        }
    }
}

let done = Button.Done("Done")
let doneButton = done.toUIBarButtonItem()

Hope that helps, feel free to ask questions about why this works if you have any!

Here is the correct code

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()
