I don't understand this exercise and how BarButton and UIBarButtonItem are related.

I would need some help in determining what parameters my function should take and the logic behind BarButton and UIBarButtonItem and how they are related.

(pls don't provide me with the code solution!)

// 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 : 
        case .edit : 

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

You are just returning UIBarButtonItem in your function. You can use UIBarButtonItem anywhere, it is not specific to this challenge. Type it into your playground and option click it if you would like to know more about it.
