XCode: Programmatically enable a symbolic breakpoint?

Question

Is there a way to programmatically enable a breakpoint? Normally I'd use a breakpoint condition, but I need to use a symbolic breakpoint.

Specifically, something is changing the contentOffset of my UIScrollView between a call to scrollToIndexPath and a call to reloadData. I'd like to enable the symbolic breakpoint only after the call to scrollToIndexPath.

Jim Ingham's answer works on a x86 system. For an iOS device I was able to use the method described in this answer to programmatically create a breakpoint. Inserting the line

asm("svc 0");

Causes the debugger to stop on the following instruction in XCode.

Interestingly if you're not connected to XCode the program continues to execute normally.
