"npx react-native run-ios" is picking non existing simulator

Question

As per https://reactnative.dev/docs/environment-setup, I'm trying to run sample project on iOS simulator

When I ran command npx react-native run-ios getting error

info Found Xcode workspace "AwesomeProject.xcworkspace"
error No simulator available with name "iPhone 12".

From where does it picking iPhone 12, I don't have that simulator in first place

Answer 1

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"

Answer 2

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

1. Accept XCode licence aggreement:

sudo xcodebuild -license

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

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

3. Make sure you have chosen command line tools on XCode:

Xcode => Preferences => Locations

Answer 3

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.

Answer 4

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

Answer 5

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

Answer 6

Now you need to run the app like this with double dashes two times:

For simulator:

 npm run ios -- --simulator="iPhone SE (3rd generation)"

For real device:

 npm run ios -- --device="your iPhone name here"
