Here is the body, see if you can figure out the rest of the challenge

    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)
    }
}
