Answer 1

Put a breakpoint at objc_exception_throw and run your app via Debug instead of Run

To clarify, what you're actually seeing when you get an exception without the breakpoint is the same stack trace always - it's the uncaught exception handler. The type of exception is logged to the Run console, but if you want to see a backtrace for where the exception was raised, that's what the breakpoint is for.
