Running On Simulator
Starting the simulatorโ
Once you have your React Native project initialized, you can run npx react-native run-ios
inside the newly created project directory. If everything is set up correctly, you should see your new app running in the iOS Simulator shortly.
Specifying a deviceโ
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 11"
. If you wish to run your app on an iPhone SE (1st generation), run npx react-native run-ios --simulator="iPhone SE (1st generation)"
.
The device names correspond to the list of devices available in Xcode. You can check your available devices by running xcrun simctl list devices
from the console.
