'bits/cpp_type_traits.h' file not found

When I try to compile a C++ program on MAC I get the following error

In file included from /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/ext/pb_ds/assoc_container.hpp:45: In file included from /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/ext/typelist.h:46: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/ext/type_traits.h:35:10: fatal error: 'bits/cpp_type_traits.h' file not found

#include <bits/cpp_type_traits.h>

Does anyone know how to fix this? If you do please let me know, help would be deeply appreciated, thank you.
