buttons.swift Code Challenge Trouble

My solution seems to work in an Xcode playground, but doesn't pass the challenge compiler.

Also, the challenge instructions say to use "UIBarButtonStyle.done" and "UIBarButtonStyle.plain", which return errors in playground, suggesting "UIBarButtonItemStyle.done" and "UIBarButtonItemStyle.plain" instead.

Any ideas as to why my code doesn't work?

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: UIBarButtonItemStyle.done, target: nil, action: nil)
        case .edit(let title): return UIBarButtonItem(title: title, style: UIBarButtonItemStyle.plain, target: nil, action: nil)
        }

    }
}

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