Is this what apple does in xcode?

  If you’re talking about the simulator, no. That doesn’t virtualize - it literally just runs it locally on your machine. Less RAM overhead and CPU since it uses your normal instruction set and doesn’t run a separate kernel and userspace.

    At least historically, it actually did run its own entire userspace, including daemons (all the way to launchd, IIRC), etc. All compiled for Intel, back in the day. Shared the kernel though. Many of the nominally shared system pieces between Mac and iPhone (like Foundation) actually had many subtle compile-time differences.
