Apple's ARM-based processor seems promising and more battery efficient than intel. What I like to know is that what low level language does it support? As for intel x86, it is primarily written in C/C++. Even though apple silicon has rosetta2 to compile third party libraries, will it still natively support low-level languages like x86_64(c/c++).
we are under NDA for deeperr details, but from Apple docs, You will be allowed to make projects in Xcode using:
C C++ Swift ObjC in ANY combinations
there are some limitations in using ASM, as per Apple docs.
