But it can be that Apple hasn't implemented it as most of their focus is on Swift, not C++.

Paavo Helde <eesnimi@osa.pri.ee>: Nov 21 12:14AM +0200 > Xcode 14.1, set target 20   XCode is just an IDE which will call some compiler underneath (clang or g++). I've not used it in last 15 years, but I'm sure some googling will help how to find out the version of g++ it's using, and how to upgrade it if necessary.

In their environment gcc/g++ are links to clang/clang++.
