Whenever you see a 0x8badf00d that means you are getting killed by the launch watchdog. Your app is taking too long to return from -applicationDidFinishLaunching.... Normal Core Data related causes to this are:
- Trying to import data in the
-applicationDidFinishLaunching... - Trying to perform a migration from
-applicationDidFinishLaunching...
To solve this you need to change your start up. The creating of the Core Data stack should never be done in the -applicationDidFinishLaunching.... Instead let the -applicationDidFinishLaunching... finish and then stand up the Core Data stack. If a migration is needed (you can check this pretty easily) then present the user with a UI informing them of the delay and then kick it off.
In either case you need to return from the -applicationDidFinishLaunching... as fast as possible, you should only be creating UI elements in this method; you should not be accessing Core Data at this point.
