gobjc is the ObjC runtime of GCC. Therefor clang does not include gobjc headers.
libobjc2 is the free drop-in replacement for the GCC runtime by the GNUstep project. It is meant to be used together with clang.
libobjc2 supports the following features above and beyond the GCC runtime (copied from the project's README, MIT license):
There are no official Debian packages for libobjc2 yet. Packaging work in progress is done as part of the Nextspace project.
The wish #680784 may be removed as it does not seem to provide a sufficient solution.
