It seems like "Open using Rosetta" was removed from "Get Info".
If you want to run project in the simulator under Rosetta, try this:
Xcode -> Product (in the menu bar) -> Destination -> Destination Architectures -> check 'Show Rosetta Destination'
After that, all devices in the build list should be able to have '(Rosetta)' in the end , e.g. iPhone 15 (Rosetta)
And the project should be able to run on these Rosetta simulator.
