Xcode debugger stopped displaying local and self variables

Question

I don\'t understand this at all, but I can no longer see any locals or ivars when debugging my iPhone app with Xcode 3.2.3. Everything seemed normal until yesterday afternoo

Answer 1

In my cases it was the optimisation for debug.

In the build settings Optimization Level was set to Fastest for both Debug and Release. I switched Debug to None and it solved the issue.
