Need help with EXC_BAD_ACCESS (code=2, address=0x0)

Hi guys!
I am trying to get my prototype onto iPhone.
But first I want to try it in xcode simulator.
The build won't go any further than "Made with Fusion" splash screen,
it becomes black and I receive this mistake

Thread 1:EXC_BAD_ACCESS (code=2, address=0x0)

Any idea on how I can solve it?

What version of Xcode are you using?. Make sure you are using the latest version.
Also, what IPhone model are you using in the simulator. ?
IPhone 6.0 does not work
