I guess this is the same reason HyperKit exists for macOS. So Apple can switch to Arm for Desktop or run iOS Apps on macOS. But I still don't get how BitCode fits into this. It seems like 2 separate teams at Apple had to tackle the problem on how to run apps on different architectures. One solution is BitCode, the other HyperKit, which would be used like a new Rosetta (PowerPC -> x86), but from (x86 -> arm64)
