I don't understand what I am supposed to do.

And it says there are comments below to help but there are no comments. I tried my best but this is incorrect.

buttons.swift 
// Example of UIBarButtonItem instance
// let someButton = UIBarButtonItem(title: "A Title", style: .plain, target: nil, action: nil)

enum BarButton {
    case done(title: String)
    case edit(title: String)

     func button() -> UIBarButtonItem {
        switch self {
        case .done:
            return UIBarButtonStyle.done
        case .edit:
            return UIBarButtonStyle.plain
        }
    }
}

let done = BarButton.done(title: "Save")
let button = done.button()

Check your switch case. You need to return UIBarButtonItem instead of UIBarButtonStyle

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)
}
