Not sure what I'm doing wrong here. This compiles correctly in playground and seems to be accomplishing what is asked...

I have to import UIKit in playground which I do but on this site it throws an error regarding UIKit. If I remove UIKit it doesn't compile and doesn't give any error to follow in preview

buttons.swift 
import UIKit

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

The last sentence in this challenge isn't asking you to edit constant "done" that you've created in 1/2 part(let done = BarButton.done(title: "Save") ) of this challenge, it wants you to create another one called "button"(let button = ... ) and do something with it . So you gonna have 2 constants("let done = ..." and "let button = ... ") in the end of this task.

Your button() is everything correct and also with UIKit everything is fine. Hope you handle it!
