For some reason I couldn't use -framework Foundation using brew installed clang

$ /usr/local/opt/llvm/bin/clang -Wall -framework Foundation a.m
a.m:1:9: fatal error: 'Foundation/Foundation.h' file not found
#import <Foundation/Foundation.h>
        ^~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

but using Apple built, /usr/bin/clang -Wall -framework Foundation a.m so feel free to check your list of installed clang maybe using where clang
