Bad Access Error in DisplayManager.mm

Can't find what caused this, maybe somebody knows ?

Unity 5.2.2.p3, Xcode 7.1, Mac OS El Capitan 10.11.1, iPod, iOs 9.1

I have Bad Access Error in this line of DisplayManager.mm :

• (BOOL)displayAvailable:(UIScreen*)targetScreen; { return self[targetScreen] != nil;

} - (DisplayConnection*)display:(UIScreen*)targetScreen { return self[targetScreen]; }

Because of NIL in the argument.

It seems when calling UnityUpdateDisplayList() method in Unity, iOs gets back null result.

Can somebody help me ?

Thx
