Sort of straw-grasping I would try with Xcode under these circumstances…
Try changing the target CPU/OS setting to something else, build, and see if the
indexing works.
If it does, make the minimal changes needed to appropriately build your target.
If it doesn’t, discard straw.

Change your .c files to .m. Then you can use objective-c calls _in_ your C
code.
Objective C is a proper superset of C, and so you just need to inform the
compiler of your intent by changing the file extension(s).
