I am building a scientific app (MacOS) that has a lot of C code being called by swift that needs to be built for X86 architecture. I have built the app and sent it to an M1 Mac computer, where Rosetta worked properly and the app was translated to arm64 seamlessly. However, now I am submitting the app to the App Store and I don't know how to get Xcode to create an archive that doesn't compile for both Apple Silicon and Intel. The option in the target build settings is simply (Standard Architectures (Apple Silicon, Intel)). Am I missing something on how to just have it archive for Intel processors? Thanks in advance

I built a MacOS app (SwiftUI 2.0 and Swift 5.3) that calls a high-performance RUST executable binary for the scientific portion. How can I wrap this up to get it ready to be distributed in the App Store? I have read a number of articles, but they seem to be a bit dated.
