You may want to read through this thread: https://developer.apple.com/forums/thread/787500
tl;dr - No
This is not supported indeed.
The feature availability is documented here if that helps: https://support.apple.com/en-us/120468
The thread referenced by RickMaddy has a lot of backstory here, but I want to address this bit specifically:
does xcode in guest work?
Xcode does work in the guest but with one significant limitation: You can’t run Mac apps that use restricted entitlements [1]. For some folks that’s a complete showstopper. For others it’s a non-issue.
If this a problem for you, I recommend that you watch the above-mentioned thread where I’ve been posting updates about new developments in this space.
Oh, and all of the above is assuming you’re on Apple silicon. The story for Intel-based Macs is very different.
