I'm also experiencing this issue. After installing Xcode 14.3 Beta 2 I cannot deploy/run my app to simulators using XCode 14.2, I encounter the same issues as OP. "Fixing" the build issues may be a valid recourse in some cases, but I do not have the time to fix everything right now. I would expect the previous release version of Xcode (14.2) to function correctly as it did before installing Xcode 14.3 beta 2 but it is not. Apple, please fix this!
