The practical reality is arguably more important than beliefs. Apple has, as it turns out, invested in trying to make Swift more suitable for kernel and similar development, like trying to automate away reference counting when possible, and also offering Embedded Swift[0], an experimental subset of Swift with significant restrictions on what is allowed in the language. Maybe Embedded Swift will be great in the future, and it is true that Apple investing into that is significant, but it doesn't seem like it's there.

And considering Apple made Embedded Swift, even Apple does not believe that regular Swift is suitable. Meaning that you're undeniably completely wrong.

You show a lack of awareness that ISO C and C++ are also not applicable, because on those domains the full ISO language standard isn't available, which is why freestanding is a thing.

But freestanding is not experimental, unlike Embedded Swift according to Apple. And there are full, large OS kernels written in C and C++.

You continue being undeniably, completely wrong.

Is it really? It always depends on which specific C compiler, and target platform we are talking about.

For Apple it suffices that it is fit for purpose for Apple itself, it is experimental for the rest of the world.

I love to be rightly wrong.
