iOS Build Integer literal is too large to be represented in a signed integer type

I am building my game for iOS. When I press play on xCode to simulate on my device, I get around 400 errors that say:> Integer literal is too large to be represented in a signed integer type> Implicit conversion loses integer precision Furthermore, I believe that these errors are breaking my game. When I play my game on my device, many aspects of the game that work perfectly fine in the unity simulator completely break.
