Just wont compile, but compiles fine in an XCode Playground?

For some reason this code won't compile for me, but when I click on the "preview" button, I don't see any errors. That, and when I copy paste all of this example into an XCode Playground, it compiles fine.

Any suggestions would really be appreciated.

Thanks in advance ...

You need to use string interpolation for the string values inside the return statement.

Sorry about that. I thought I opted for it to be posted w/my question.

Here you go:

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

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

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

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

And your constant created in the first video is not initialized. You need to create original constant, and then pass that in with new constant
