I should have mentioned that I am aware of Apple's deprecation notice in the release notes. But the note refers to Xcode 14.3 Beta and doesn't say that Xcode 14.2 couldn't be used to build x86 Simulator builds anymore.
With regard to your suggestion: I have a complex client project setup that I cannot really tinker with a lot. It worked with Xcode 14.2 prior to the installation of Xcode 14.3 Beta (in addition to Xcode 14.2). I am afraid what you suggest is not really an option for me.
Maybe removing 14.3 beta and re-installing the existing XCode 14.2 (even if you already have it) will add the functionality that seems to be removed with 14.3 beta?
Given that building like 14.2 alone allowed is more of a priority than having 14.3 beta.
Can also try to install macOS on VM on your Mac, and keep that with just 14.2 there for builds.
