This was confusing the hell out of me. I’d have an fprintf call that would say something like “loading spectra…” and a breakpoint before that and in the console it would still print “loading spectra…” and continue on its merry way like the breakpoint didn’t even exist.

So what’s the real problem? I don’t know for sure, but I fixed it by “Clean all targets” and then rebuilding. It’s like XCode didn’t know a change had been made to the code when I would simply do a normal build. In fact, that’s been a problem that’s come up a good amount over the past few weeks. I’ll make a code change, build and nothing. No change. It’s gotten to the point that I have an fprintf call that I modify with each build so that I can see if changes really have been used.
