Answer 1

There is a solution that I usually use on my projects, setting up some special breakpoint. To do that:

1. Open XCode
2. Goes to "View -> Navigators -> Show Breakpoint Navigators"

Now add some new breakpoints clicking the "+" button:

• Add exception breakpoint
• Add Symbolic breakpoint with symbol [NSException raise]
• Add Symbolic breakpoint with symbol objc_exception_throw

Run again your project, application will stop on the line that is causing your problems.
