"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
