Finding Closure

You may already be familiar with closures. They’re fairly common in most programming and scripting languages, such as Ruby and Javascript (they’re used extensively in JQuery), though some languages have introduced them only recently (such as PHP).  If you are not, then this article will help introduce you to closures and explain how they are used in Swift.
