I use something like this...

Code:

#if TARGET_IPHONE_SIMULATOR

        #define PRIMITIVE_Break() \

            __asm { int 3 };

    #elif TARGET_OS_IPHONE

        #define PRIMITIVE_Break() \

            asm {trap};

    #endif

Okay, this is something new to me. Why would you want to do this versus using a break point in Xcode?

As far as I know (and this is how I am using it), these "DebugBreak" instructions are mostly used in assert macros. Whenever one of you assertions fails, you application will break in the debugger (whatever the project you are working on vs. one project per breakpoint).

Awesome thanks Ozirus!

That worked. And to answer Malarkey's question it's for my custom assert class.

If you don't use assert you should, when something bad happens you get to find out about it without incurring the overhead for release builds.
