Support for Xcode 14.x

[thiagohmcruz]

As of 4fd6d12 Xcode 13.3 is the latest one supported. A lot of us are already on Xcode 14.x so worth following the UPDATE guide to add support for it.

I guess the question here is if we want to add support for all 14.x version or only the latest?

This should be added to: rules_xcodeproj: Build with Proxy

I'll accept updates to support newer Xcode versions, but I'm currently rewriting the project (with an unspecified first public commit date, though at least a few weeks out) to have a different multiple Xcode version support model (which will support Xcode 14.1+).

Ok, thx for the context, def not suggesting we push for that now. Intent was to add as a thing to do in that project. Since you're rewriting I assume that's already covered then!
