Can you mark the exact line due to which app is crashing?

App is crashing at this only line and raising kern exec 3. If I comment this line, I am getting the same panic in every next line of code

Does it happen in the emulator or on a device?

on emulator

You can check it out whether its happening in device or not. According to me, if iSession is not NULL then it should not crash. Also, you are using TRAPD there.

I am getting same on device also
