Here is a chunk of code That I created for you. It moves a character back and forth 3 times printing when the edge of the screen is reached and switch the direction. After the third iteration it stops and tellls that the race is completed: http://swiftlang.ng.bluemix.net/#/repl/57c64a92c62de72752d32274
