At WWDC ’14, Apples has launched Swift, a brand new Xcode Programming Language, which seems to howtshine Objectve C when it comes to performance and syntax simplicity.

Here the Apple press release:

“Swift is a powerful new programming language for iOS and OS X® that makes it easier than ever for developers to create incredible apps. Designed for Cocoa® and Cocoa Touch®, Swift combines the performance and efficiency of compiled languages with the simplicity and interactivity of popular scripting languages. By design, Swift helps developers write safer and more reliable code by eliminating entire categories of common programming errors, and coexists with Objective-C® code, so developers can easily integrate Swift into their existing apps. Xcode® Playgrounds make writing Swift code incredibly interactive by instantly displaying the output of Swift code.”
