2,073 PointsImpossible exercise, nil selector won't compile
Hello folks, the exercise asks to pass nil as the "action" parameter but then the code won't compile. Maybe it's because i'm using swift 3. I changed the "action" property in the UIBarButtonItem to be optional so a nil value will pass. It works in my playground, but not in your web editor... again I'm afraid it's because of the swift version.
Best, Ivan
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(String)
case Edit(String)
func toUIBarButtonItem(title: String) -> UIBarButtonItem {
switch self {
case .Done: return UIBarButtonItem(title: title, style: UIBarButtonStyle.Done, target: nil, action: nil)
case .Edit: return UIBarButtonItem(title: title, style: UIBarButtonStyle.Plain, target: nil, action: nil)
}
}
}
let doneButton = Button.Done("DoneButton")
