When you say “low level” language, i think of how C is pretty light when compiled and can be compiled for embedded projects, like arduino, as opposed to pi, which as enough meat to instantiate a linux os.

I have seen server side swift. Do you know of embedded examples of swift, that may be compiled down to a non-os chip level firmware? Since this can be done for C, i don’t see why it couldnt be done for swift. You just need compilers for popular chips like st32 from st micro, or msp340 from ti or PIC?
