> To disable the in-app developer menu for production builds of your application, open the project in Xcode and navigate to `Product` → `Scheme` → `Edit Scheme...`(or press `⌘ + <`), select `Run` from the menu on the left, and change the Build Configuration to `Release`.
### Reload
Selecting Reload will reload the iOS application (this is the same as pressing `⌘ + r` in the iOS Simulator).
### Chrome Developer Tools
To debug the JavaScript code of your React app in Chrome, either select the option from the developer menu or press `⌘ + d` to open the in-app developer menu, select `Debug in Chrome`, and a webpage should open up at [http://localhost:8081/debugger-ui](http://localhost:8081/debugger-ui).
Press `⌘ + Option + i` to open the Chrome Developer Tools, or open it via `View` → `Developer` → `Developer Tools`.
You should now be able to debug as you normally would.

> To debug on a real device: Open the file `RCTWebSocketExecutor.m` and change `localhost` to the IP address of your computer. Shake the device to open the development menu with the option to start debugging.
Install the [React Developer Tools](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en) extension for Google Chrome. This will allow you to navigate the view hierarchy if you select the `React` tab when the developer tools are open.
