Question

Excuse my ignorance, but something\'s been bugging me about the Xcode debugger when running iPhone applications in the iPhone Simulator.

The lack of a stack trace is usually indicative of a problem with LLDB (debugger). I love LLDB, but when it comes to showing stack traces and breaking on the exception rather than main in iOS apps, it's a pain in the ass and has been for a few releases now. No idea why Apple hasn't addressed this yet. To fix it is a two-step process:

1. Edit your current scheme and under the "Run" tab change the debugger from LLDB to GDB.
2. Go to https://developer.apple.com/bugreporter/ and report the bug so Apple addresses it.
