React Native - Running IOS

If you want to test your app in the IOS simulator, all you need is to open the root folder of your app in terminal and run −
react-native run-ios
The above command will start the simulator and run the app.
We can also specify the device we want to use.
react-native run-ios --simulator "iPhone 5s
After you open the app in simulator, you can press command + D on IOS to open the developers menu. You can check more about this in our debuggingchapter.
You can also reload the IOS simulator by pressing command + R.
