I recently updated my xcode to latest version 12.2. According to the doc I should be able to see 64 bit arm selection in the architectures list. But I don't see that. Am I missing something?
Do I need my macOS updated to Big Slur in order to use xcode 12 to target macOS arm64?
You do not need to be on Big Sur. I'm still on Catalina, and the Architectures build setting says Standard Architectures(Apple Silicon, Intel). When I build with the Release configuration, I get a fat binary with Intel and Apple Silicon versions of the app.
What architectures are in your list? That may help someone provide an answer for you.
