For the Objective-C developers yet to explore Swift. Julius Parishy:

“…I’d like to show some of the more stubborn Objective-C developers the benefits they will receive from adopting Swift, be it now or later. To begin, let’s discuss the concept of Optional Values, a new feature in Swift that is not available in Objective-C.”

Julius provides a good introduction to Swift optionals with numerous examples.
