How to create static library for iOS without making all symbols public

This question has been asked before, but digging into the documentation for the various development tools it seems like this is possible, just not obvious. Motivation: Making a static library for use by other iOS developers. Some symbols in the library will cause problems if exported so I wish to make them internal-only symbols. With a dynamic library this is easy, just use -exported_symbols_list
