You can also connect to the development server over Wi-Fi. You'll first need to install the app on your device using a USB cable, but once that has been done you can debug wirelessly by following these instructions. You'll need your development machine's current IP address before proceeding.

Open a terminal and type ipconfig getifaddr en0 For MAC

Make sure your laptop and your phone are on the same Wi-Fi network. Open your React Native app on your device.

You'll see a red screen with an error. This is OK. The following steps will fix that.

1. Open the in-app Developer menu. shake your phone or press CMD/ctrl + M
2. Click on Settings
3. click on Debug server host & port for device
4. On popup Type your machine's IP address and the port of the local dev server (e.g. 10.0.1.1:8081).
5. Go back to the Developer menu and select Reload.
