Perhaps Unity's cross platform technology is implemented through a Mono virtual machine. This virtual machine update is too slow to adapt to many platforms. unity has developed IL2cpp on its own, converting the intermediate code running on the virtual machine that should have been mono to CPP code, so that the generated CPP code...
