I'm trying to build C project with XCode 15.0, but always get error 'assert.h' file not found. I tried to clean and restart XCode, reinstall XCode and reboot, set different framework versions and project formats.
I found all entries of stdarg.h with Finder and made sure, that all directories, containing stdarg.h, contain also assert.h, but stdarg.h includes are resolved, assert.h - not. How could this be ? Many thanks for any help.
Ventura 13.6, M2, Command line tools version 2397
