iOS Enumerations and Optionals in Swift Introduction to Enumerations Enum Methods

Need help with returning associated values in an instance method

I am stuck. I feel like I pretty much followed the instructions. I created an instance method in the enum. I am returning UIBarButtonItem with the parameters in the instructions.

Playground is giving me an error so clearly something is not able to compile. I just don't know where I went wrong.

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(title: "Done"): return UIBarButtonItem(title: "Done", style: UIBarButtonStyle.done, target: nil, action: nil)

        case .edit(title: "Edit"): return UIBarButtonItem(title: "Edit", style: UIBarButtonStyle.plain, target: nil, action: nil)

        }
    }
}

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