Crash is not for this code ..somewhere you are using.
Set a breakpoint on objc_exception_throw, then build the app for debug, run the app with breakpoints on and cause the crash again, then go up the stack to the relevant code.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
