Swift is the new programming language introduced by Apple. It is supposed to be faster, clearer, and more computationally effective than Objective-C. Swift is completely native to Cocoa and Cocoa Touch. The Swift code can fit alongside Objective-C and C code in the same application. In the Swift playground, you can see your programming essentially as a live preview. Swift will be available to developers "right out of the gate."
