You can display the console logs for an iOS or Android app by using the following commands in a terminal while the app is running: RedBoxes and YellowBoxes are automatically disabled in release (production) builds.

Specific warnings can be ignored programmatically by setting an array of prefixes that should be ignored: console.ignoredYellowBox = YellowBoxes can be disabled during development by using console.disableYellowBox = true. Click on the alerts to show more information or to dismiss them.ДЄs with a RedBox, you can use console.warn() to trigger a YellowBox. Warnings will be displayed on screen with a yellow background. You can use console.error() to manually trigger one.

You have modified native code (Objective-C/Swift on iOS or Java/C++ on Android).Д®rrors and warnings are displayed inside your app in development builds.

You have added new resources to your native app's bundle, such as an image in Images.xcassets on iOS or the res/drawable folder on Android.

You will need to rebuild your app for changes to take effect in certain situations: If you run into any issues, use a full reload to reset your app. There are some instances where hot reloading cannot be implemented perfectly. This will allow you to persist the app's state through reloads. You may even go a step further and keep your app running as new versions of your files are injected into the JavaScript bundle automatically by enabling Hot Reloading from the Developer Menu. Automatic reloading can be enabled by selecting 'Enable Live Reload' from the Developer Menu. You can speed up your development times by having your app reload automatically any time your code changes. If the Command вЊ + R keyboard shortcut does not seem to reload the iOS Simulator, go to the Hardware menu, select Keyboard, and make sure that 'Connect Hardware Keyboard' is checked. You can also press Command вЊ + R in the iOS Simulator, or press R twice on Android emulators. To do so, select 'Reload' from the Developer Menu.

Instead of recompiling your app every time you make a change, you can reload your app's JavaScript code instantly. The Developer Menu is disabled in release (production) builds. You can also use the Command вЊ + D keyboard shortcut when your app is running in the iPhone Simulator, or Command вЊ + M when running in an Android emulator. You can access the developer menu by shaking your device or by selecting 'Shake Gesture' inside the Hardware menu in the iOS Simulator.
