title: Difference physics between release build and debug build on iOS
body: <p>I have an iOS game that uses Box2D. When I run it in Debug mode everything is fine. When I run it in Release mode all game objects speed up and it seems like the mass of game objects is higher or something like that. It's very strange.</p>
  
  <p>The frame rate is pretty much the same on both versions so that isn't the problem. Everything in the game should be frame rate independent anyway.</p>
  
  <p>Any idea's what project setting's in XCode might be causing this?</p>
