Code attached. Could someone explain to me what am I doing wrong?
// 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(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

enum BarButton {
case done(title: String)
case edit(title: String)
func button() -> UIBarButtonItem{
switch self {
case .done(let title):
return UIBarButtonItem(title: title, style: .plain, 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()
