In Xcode 16 Rosetta option is not available,
Actually I'm facing some architectural issue in non rosetta simulators. The code will run only Rosetta simulators.
could not find module 'module name' for target 'x86_64-apple-ios-simulator'
In Xcode 15 it's available under Product -> Destination ->Destination Architecture.
Once Mac and Xcode has restarted, the Rosetta simulators are now visible.
It's Under Product, select Destination > Show All Run Destinations to see Rosetta run destinations.
