I have tried numerous solutions. Don't understand "initializer" comment in preview. Have worked over two hours.
import Foundation
enum UIBarButtonStyle {
case Done
case Plain
case Bordered
}
class UIBarButtonItem {
var title: String?
let style: UIBarButtonStyle
var target: AnyObject?
var action: Selector
init(title: String?, style: UIBarButtonStyle, target: AnyObject?, action: Selector) {
self.title = title
self.style = style
self.target = target
self.action = action
}
}
enum Button {
case Done(title: String)
case Edit(title: String)
func toUIBarButtonItem() -> UIBarButtonItem {
switch self {
case .Done (let titleValue):
return UIBarButtonItem(title: titleValue, style: UIBarButtonStyle.Done, target: nil, action: nil)
case .Edit (let titleValue):
return UIBarButtonItem(title: titleValue, style: UIBarButtonStyle.Plain, target: nil, action: nil)
}
}
}
let done = Button.Done(title: "Done")
let doneButton : UIBarButtonItem = Button(done)

21,046 PointsHey Erin Krentz,
You're SO close!!! The only problem is with your call of the method. You need to call the method toUIBarButtonItem on done and assign it to the constant doneButton.
let doneButton = done.toUIBarButtonItem()
And that's it. The fix is as simple as that! This was a really hard challenge, I had a lot of trouble even getting to the point you got to myself!
Good Luck!
