Open Xcode and check which simulators are installed or list available simulators in terminal with xcrun simctl list devices.

Then define a simulator you wanna use:

npx react-native run-ios --simulator="iPhone 13"

I know this step but it didn't answer from where does it pick up "iPhone12" , that simulator is not even present – vikramvi Aug 26 '21 at 10:19
Your projects xcode file and check which simulator is selected – Michael Bahl Aug 26 '21 at 12:49

The argument is with a double dash `--simulator='iPhone 13'`. At least thats what worked for me. – Jason Jul 07 '22 at 21:52

@SuperUberDuper Install the simulator with Xcode first. – StoneLam Dec 02 '22 at 05:03

If you're coming from React Native, follow these:

Accept XCode licence aggreement:

sudo xcodebuild -license

Run simulator using iPhone 14, if you haven't added old iPhones:

npx react-native run-ios --simulator="iPhone 14"

Make sure you have chosen command line tools on XCode:

Xcode => Preferences => Locations

React Native will pick a particular device by default, depending on its version. As of version 0.67.2, for example, it'll try to boot an iPhone 13 by default regardless of it existing locally or not.

I was facing the same problem. Then i just run

sudo npx expo start

Resolve the incompatible dependencies it will show you.

Press " i " to run the app. The app will open on a booted simulator.

See available with :

xcrun simctl list devices

I had a similar error and I fixed it by creating a new simulator with this exact name (case sensitive) Open Simulator App > File > New Simulator > create one with the name from the error

It would help to show what app and menu this is, and how to get here. – Kevin Hernandez Nov 18 '22 at 21:18
