When testing a React Native app with react-native run-ios it opens an iPhone simulator.
You can change the virtual device to an iPad in the Simulator options, but the React Native app does not appear in the list of installed apps.
Is there a way to open an iPad simulator from the CLI?

You can specify the device the simulator should run with the --simulator flag, followed by the device name as a string. The default is "iPhone 13" . If you wish to run your app on an iPhone SE (2nd generation), run npx react-native run-ios --simulator="iPhone SE (2nd generation)" .
Expo allows us to build for both Android and iOS on Windows, Mac and Linux. You can run your React Native app on a physical device without setting up the development environment. All you need to do is download the Expo Go app, run expo start and then scan the QR code that shows up.
React Native supports building apps for iOS, Android, and web from a single code base. It's a more affordable technology than Swift, yet it allows creating high-quality apps.
--simulator flag is what you are looking for
For example react-native run-ios --simulator 'iPad 2' will run the app on iPad 2 simulator.
As a side node, if you need to get list of available simulators with their names use xcrun simctl list devices

Get device list with this command
