std::pmr::get_default_resource is available in C++17 and later, but I'm not sure when / if it was fully supported by Xcode. You might want to double check your C++ version in your project to make sure you're linking to a new enough version of libc++.

Sure, it works fine once upgrade iOS16 to iOS17. So i guess c++ lib in iOS16 without implementation of std::pmr.
