Does not show an error in a playground but does in the challenge why???

Question

In the playground this is fine but not on here, it is confusing me.

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

You're not getting a compiler error which is what Xcode would tell you. It's just that the challenge isn't seeing what it's expecting. Everything looks right, except your constant was supposed to be button not doneButton. The incorrect message appears to be wrong for the challenge:

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