Notifications provide a way to react to asynchronous events. e.g.:
NSNotificationCenter.defaultCenter()
func addObserverForName(String, // name of the "radio station"
object: AnyObject?, // broadcaster (or nil for "anyone")
queue: NSOperationQueue?) // queue to execute the closure on
{ (notification: NSNotification) -> Void in
let info: [NSObject:AnyObject]? = notification.userInfo // notification-specific information
}

The twelfth lecture addresses a different approach to animation, creating sets of behaviors defining how items should interact with each other and the environment.
First we create an animator inside a reference view:
var animator = UIDynamicAnimator(referenceView: UIView)

The keyboard appears when a text field becomes first responder (becomeFirstResponder) and desperadoes when it resigns to be first responder (resignFirstResponder). To know when the return key has been pressed (functextFieldShouldReturn) or when editing has ended (textFieldDidEndEditing) is controlled via delegates or target/action notifications.

The lecture starts with additional information on how to control the appearance of a view in different size classes and how to inspect constraints in various size classes.
Adding sub views to a scroll view works similar like adding views to any other view. The only important difference is to define the content size of the scroll view:
scrollView.contentSize = CGSize(width: 3000, height: 2000) logo.frame = CGRect(x: 2700, y: 50, width: 120, height: 180) scrollView.addSubview(logo) aerial.frame = CGRect(x: 150, y: 200, width: 2500, height: 1600) scrollView.addSubview(aerial)
