iOS Enumerations and Optionals in Swift Introduction to Enumerations Enum Methods

This task has been stressing me out I got pass it but I have no idea what the question is asking or what the cade does

Next, add a method to the enum named button that returns an instance of the class UIBarButtonItem configured properly. An example of how to create an instance for this task is shown in the comments below. Use the same initializer.

In the method, using the associated values as titles for the button, return a button with style UIBarButtonStyle.done for the done member of the BarButton enum. Similarly for the edit member, return a UIBarButtonItem instance with the style set to UIBarButtonStyle.plain.

In both cases you can pass nil for target and action. Once you have a method, call it on the value we created in the previous task and assign it to a constant named button.

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

Hey Alex,

If you're ever feeling stuck and are looking into the community questions, chances are your question has already been asked before and all you have to do is search for it in the respective language category.
