Same here, major issues on multiple projects. Some cant even build for dev. Some cant archive a build for export. All sorts of issues. Still have to use 14.2 SDK for all projects.

So I have been digging and found this: TN3117: Resolving architecture build errors on Apple silicon | Apple Developer Documentation/ And per this screenshot -> it shows this option for whats mentioned here, so I am wondering if it has to do running xcode 14.3 on intel vs apple silicon?
