Answer 1

First, symbolicate your crash log as that would help a great deal.
Second, you are getting a crash on Thread 6. Are you intentionally using Core Data on a background thread? Do you understand all of the implications of Core Data in a multi-threaded environment?
Third, do you have any console output other than the stack trace? Can you duplicate this in a debug build?

Answer 2

Thanks for giving me hint from your answer,
basically what i did wrong here is, i am running all core data operation in background thread and that lead to crash my application.
To solve this i gone through following link and after studying it i solved it and now it works like charms for me.
