change simulator on iOS

2020-12-16 hit count image

let's see how to change the simulator on iOS when we test RN(react native) on iOS.


We always use below command on RN(react native) development.

npm run ios

It’s not a problem when we develop but when we want to test RN(react native) project on the different device. It always uncomfortable. So I’ll introduce how to change the simulator by command line.

Check iOS simulators

check current iOS simulator we can use.

xcrun simctl list devices

After executing, you can see the list of the simulator like below.

iPhone 8 (066D55DB-AB0A-41D3-84A0-612E68F88063)
