iOS Swift
The delegate pattern has long been very prominent on Apple's platforms. Delegation is used for everything from handling table view events using UITableViewDelegate, to modifying cache behavior using NSCacheDelegate. The core purpose of the delegate pattern is to allow an object to communicate back to its owner in a decoupled way. By not requiring an object to know the concrete type of its owner, we can write code that is much easier to reuse and maintain.
