It’s actually not. Objective-C is a superset of C. C++ is not. It’s MOSTLY compatible…but it’s not a superset. See the restrict keyword, or the need for casting to and from void*, or the inability to name variables new or delete, or class, or this. I can’t count how many C projects I have which use this as a variable name that WILL NOT compile as C++…or the need for extern C to call C ABI code…in no way is it a superset
EDIT: lol, you can downvote me if you want but I think you need to lookup what a superset is
