iOS Enumerations and Optionals in Swift Introduction to Enumerations Enum Methods

Hi, I am having issues with this challenge. The following code compiled in xcode and but fails the code challenge

enum BarButton { case done(title: String) case edit(title: String)

func button () -> UIBarButtonItem {
    switch self {
    case .done (let title) : return UIBarButtonItem.init(title: title, style: UIBarButtonItem.Style.done, target: nil, action: nil)
    case .edit (let title) : return UIBarButtonItem.init(title: title, style: UIBarButtonItem.Style.plain, target: nil, action: nil)

    }
}

}

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

buttons.swift
enum BarButton {
    case done(title: String)
    case edit(title: String)

    func button () -> UIBarButtonItem {
        switch self {
        case .done (let title) : return UIBarButtonItem.init(title: title, style: UIBarButtonItem.Style.done, target: nil, action: nil)
        case .edit (let title) : return UIBarButtonItem.init(title: title, style: UIBarButtonItem.Style.plain, target: nil, action: nil)

        }
    }
}

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

I've come to realise that the UIBarButtonItemStyle suggested in the code challenge doesn't work in xcode because it's been "obsoleted" so it's probably a good idea to call that out properly so students don't waste lots of time. Or perhaps update your code challenge to use the latest swift version
