I have written code that produces no compiler errors in Xcode yet treehouse assumes there are compiler errors (none are shown in preview window either)
When I use
import UIKit
treehouse throws a compiler error. When I don't Xcode throws a compiler error. Either way something is wrong here.
// 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 GetUIBarButtonItem() -> UIBarButtonItem {
switch self {
case .done(let title): return UIBarButtonItem(title: title, style: .done, target: nil, action: nil)
case .edit(let title): return UIBarButtonItem(title: title, style: .plain, target: nil, action: nil)
}
}
}
let done = BarButton.done(title: "Save")
let button = done.GetUIBarButtonItem()

In the question they ask you to name the method as 'button'.
enum BarButton {
case done(title: String)
case edit(title: String)
func button() -> UIBarButtonItem { // I renamed the method to button.
switch self {
case .done(let title): return UIBarButtonItem(title: title, style: .done, target: nil, action: nil)
case .edit(let title): return UIBarButtonItem(title: title, style: .plain, target: nil, action: nil)
}
}
}
let done = BarButton.done(title: "Save")
let button = done.button() // Now I'm calling 'button'
Hope this helps =)
