Hello,
I'm not 100% sure, but I think this task is outdated. Here is why: 1) There is no such class like UIBarButtonItemStyle. There is the new enum - Style in the class UIBarButtonItem at the moment. 2) I can't import UIKit. So I can't get the implementation of UIBarButtonItem.
// Example of UIBarButtonItem instance
// let someButton = UIBarButtonItem(title: "A Title", style: .plain, target: nil, action: nil)
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: UIBarButtonItem.Style.done, target: nil, action: nil)
case .edit(let title):
return UIBarButtonItem(title: title, style: UIBarButtonItem.Style.plain, target: nil, action: nil)
}
}
}
let done = BarButton.done(title: "Save")
let button = done.button()

True, but there is UIBarButtonItem.Style which is very close and has the same exact cases, so if you just use the .case syntax, you won't have any issues.

You don't have to. That is taken care of for you.
