Thanks for the advice. Since we last spoke I've gone through the iOS tutorial and with my limited knowledge of working Xcode, I was able to get a target set for all 3 targets I wanted to implement: (Intel, M1, and iOS Architectures). This is all within the same Xcode project.
I wasn't able to figure out how to combine the Intel & M1 architectures into the same Xcode target though. Oh well.
