Objective c probably will be phased out before C will. Objective-C libraries are themselves a wrapper over optimized C, which is what constitutes most of ios core.

I don’t think swift will phase out C until a very long time. It still needs to sort its performance issues related to memory automatic reference counting and global lock. Which requires something close to rust borrow checker, but with an even more advanced technology to keep the syntax beginner friendly.
