That’s exactly what the access modifiers are supposed to do. A framework is by definition a separate package from the binary that imports it, so only public symbols are visible.

This doesn’t only apply to Obj-C code, either. Swift code in your app won’t be able to use internal APIs of Swift code from the framework, either.

This seems to be pretty clearly the correct behavior, so I can’t see it being changed.
