Can't progress

Hi, the editor tells me I need to add a constant named "doneButton", which I did do. I can't check the preview either. I also tried someone else's code from the forum which did not work either.

buttons.swift 
enum Button {
    case done(title: String)
    case edit(title: String)


    func toUIBarButtonItem() -> 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 = Button.done(title: "Done")
let doneButton = done.toUIBarButtonItem()
