My app crash after downloading it from appstore?

EDIT: Look at lines 10 and 11 from your stack trace.

Plug your device into your Mac, open up XCode organizer and import the crash reports. You should be able to symbolicate them and use the stack trace to determine the cause of the crash.

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.
