EDIT Swift 4.x

let app = UIApplication.shared.delegate as! AppDelegate

If you're e.g. not in a ViewController, you must:

import UIKit

Perhaps try:

let app = UIApplication.sharedApplication()

EDIT (Swift 3):

It should be noted that in Swift 3, to accomplish this, you will want to access the shared property instead:

let app = UIApplication.shared

And btw. - don't forget to `import UIKit` if you're e.g. not in a ViewController – Thomas Fankhauser Oct 01 '14 at 14:48

You are right, I got the same problem and it was the missing import. – Hola Soy Edu Feliz Navidad Mar 11 '15 at 10:26

Just to note, for Xcode 8 / Swift 3, it's just: UIApplication.shared – Ruiz Aug 17 '16 at 12:32
