Ios game crashes but on android it works fine

So i made a game for android,its 2D game with 30 textures per level,15 level(some texture are same for every level and etc)Maybe 50 textures are in resources folder and the rest is in sprites folder.I have about 30 sounds,all together less then 10mbs,and the whole game for android is aroung 60mb.
I ported it for iOS and added google mobile ads framework into xcode and the game installed and main menu was good,it lagged at first 2 seconds but it started working normally(probably while it was opening).Ads showed up on main menu and settings menu,as well as on scene where you choose levels,everything worked great,and then i pressed play,everything stopped and freezed except sound that was going in background.Xcode didnt make any exceptions as far as i could see.

 

Hi.
Did you solve this?
I have a possibly related issue:
