Download Xcode 6 Beta 5 to view code in Xcode with no errors. Code will unfortunately not run for you due to beta IDE error AND I believe you need an Apple Developer's license to download the beta. In addition, Swift code cannot be sent to Apple until the official release of Xcode 6, iOS 8, and OSX Yosemite in the fall (2014). Think of how happy users will be to use iOS 8 though! Here is a demonstration video of what this code does currently because you (sadly) can't run it : https://www.youtube.com/watch?v=8V3t3sh-128&feature=youtu.be
Have a happy day! :)
