It goes even further their beloved C code is compiled in compilers written in C++, including the standard library, exposing C++ implementations as extern "C" functions.

It is a pity that Microsoft backtracked on their C support.

WWDC is happening this week, one set of announcements at State of the Union was how Apple replaced a few C, Objective-C and C++ components, including at OS level with Swift.

Interesting. I'm know nothing about Apple, but maybe you can explain how idiomatic Swift handles Blobs and how that interfaces with C or C++ around void ptrs, std::spans etc.?

Those are unsafe buffers, and have specific primitives to handle them, Swift also has span, and interoperability with Objective-C and C++ code.
