Xcode debugger is slow when setting "conditional" break points?

Question

I use Xcode 5 to program with C. I lately noticed that the debugger in Xcode was very slow when setting a "conditional" break points. If I remove any condition, debugger runs in normal speed. I wonder if there is something I should have set in Xcode configuration. Does anybody have any suggestion?

Answer 1

Even if the breakpoint doesn't cause a stop, the debugger still needs to take control of the process every time to evaluate the condition.

If you need skip a conditional branch many times, it is often better to add the condition to your source, set the breakpoint on the new source, rebuild and rerun.

Answer 2

I have observed very slow debugging when 'Queue Debugging' is enabled in XCode.
