iOS Crash without Error or Stack Trace
Try reading the registers.
Whenever my app crashes without error, in most cases I have found the exception in the registers.
First go to Exceptions tab and 'Add Exception Breakpoint' using the + at the bottom left corner.
Then when the app crashes click on "0 objc_exception_throw" under Thread 1
Finally in the console enter:
register read(you should get a list of registers)
po $rax (normally the exception is in 'rax')
(you should see the exception output on the console)
Hope this helps.
For lack of a better solution, and if it isn't obvious, pepper your app with NSLogs to circle where this occurs, then drill deeper from there via breakpoints and/or additional logs.
Super late answer, but I've found that using try/catch helps give information when I can't get a stack trace and my application pulls a Keiser Soze.
@try{ // suspected code causing crash/errors}@catch (NSException *exception){ NSLog(@"Exception: %@", exception);}
