AFAIK none of the (current) apple produced processors do 32 bit, even the apple watch. Which is interesting, as it is very memory constrained, the usual reason for using 32 bit code. Judging by some LLVM patches by an apple engineer, they solved this by creating an ILP32 mode for Aarch64 where they use the full 64 bit mode but with 32 bit pointers.
