Xcode 13 - Previews running extremely slowly

I have just upgraded Xcode from 12.x.x to 13.0 and now "Previews" are taking several minutes to compile, in fact still running as I raise this call, compared to a few seconds previously on my MacBook Air (M1).

Anybody else having the same issue and is there a fix?

Same issues. Constant out of memory, lags, freezes.. omg. It's amazing how such a huge company is making such a crap products.. This garbage is unusable.
