I completely agree, but I was happy there was at least a workaround. Currently our list is about 400 entries long, and it's a pain to maintain. In this case nm is your friend (though it still requires hand editing). Good luck! Stephen _______________________________________________ Do not post admin requests to the list.

I already have visibility override #pragmas around the Objective C functions I want exposed. It would be a lot easier to just have "hide EVERYTHING *except* these 5 things). You can do that. There's a setting for both "exported symbols" and "unexpected symbols" in the target settings of the Xcode project. So you can use either a white list or a black list, and I think there's even a way to do both at the same time if you need to for some reason.

I've found that symbols are not necessarily hidden unless you hide the symbols upon compile (using the hidden flag for visibility), and THEN also strip the binary afterwards. _______________________________________________ Do not post admin requests to the list.

As long as release builds are fully locked down, I'll be happy. Will give nm a try thanks! I just mostly wanted to make sure that it was ACTUALLY doable, without massive namespace changes.
