That’s a quick one. In the last completion block of the destroy animation check if there are any bricks left:
[swift]
private func destroyBrickAtIndex(index: Int) {


UIView.animateWithDuration(1.0, animations: {

}, completion: { (success) -> Void in


if self.bricks.count == 0 {
self.levelFinished()
}
})

}
[/swift]

Remove all balls from screen, and display the alert. When the alert gets confirmed regenerate the bricks:
[swift]
func levelFinished() {
for ball in breakout.balls {
breakout.removeBall(ball)
}

let alertController = UIAlertController(title: "Game Over", message: "", preferredStyle: .Alert)
alertController.addAction(UIAlertAction(title: "Play Again", style: .Default, handler: { (action) in
self.levelOne()
}))
presentViewController(alertController, animated: true, completion: nil)
}
[/swift]

The complete code for step #4 is available on GitHub.
