iOS - Xcode 5 Clang Error

I was making a prototype in Xcode 5 and there were a lot of error so I decided to come back to the drawing board and start a new project. When I created the new project it had a clang error just like the last one.

Here is what it says

Looks like you have two global variables _i, one in Game.m and one in Test.m files. Just make them static if you don't need them to be visible in the whole program.
