Exploring UIAlertController (Permalink)
Ash explains the new UIAlertController that replaces UIAlertView in
					
					iOS 8 and gives you some examples how to use the new APIs in Swift. He writes:
				
The new UIAlertController has some great benefits:
It’s explicit
It conforms to iOS composability conventions
It’s got a clear API
It’s reusable in different contexts (iWatch vs iWatch mini)
The drawbacks are:
It’s unfamiliar
					In other words: UIAlertView is easy, UIAlertController is simple.
