Is there an option to toggle "Open using Rosetta" value for a specific app using Terminal?

Question

I'm really tired of checking this option manually for Xcode, which I cannot duplicate due to its size... maybe there is a way to create some kind of shortcut to launch an app (Xcode in my case) with the specific value of "Open using Rosetta"?

Note: this question relates only to Apple Silicon Macs.

Example of the "Open using Rosetta" option in Finder:

LaunchServices are keeping track.

See ~/Library/Preferences/com.apple.LaunchServices/com.apple.LaunchServices.plist: Architectures for arm64 dictionary.

I've decided to create a tiny menu bar app instead of writing a command each time.. I think I will make it public and then post a link here ;) – goldwalk Apr 20 '21 at 09:03

Modifying com.apple.LaunchServices.plist only works after reboot. You could call the private function _LSSetArchitecturePreferenceForApplicationURL defined in CoreServices.framework. This is what finder does when you check/uncheck "Open Using Rosetta."

I have created a small utility that does this: https://github.com/tapthaker/SetArchPrefForURL
