Question 34741 in React native Question posted in
The official React Native documentation can be found here.

Is the "Loading from metro…" screen only for development, or can I remove it? – React native

I created a new app using `npx react-native init MyApp’ which uses the default template. When I run the app both in the simulator and live on my device (iPhone), this happens:

  1. Splash screen shows for a moment
  2. "Loading from metro" screen shows for several seconds – overwriting my splash screen

enter image description here

  1. Main app screen shows

My question is: does this metro screen only show for development and if I publish in the App Store it will not appear? Or is there a way to hide it and go direct from the splash to the main app screen?

    The screen is shown just in the development mode and won’t be seen when you debug or release build your application, just try it by

    FOR ANDROID

    Step 1: Go to the root of the project in the terminal and run the below command:

    react-native bundle –platform android –dev false –entry-file index.js –bundle-output android/app/src/main/assets/index.android.bundle –assets-dest android/app/src/main/res

    Step 2: Go to android directory:

    cd android

    Step 3: Now in this android folder, run this command

    ./gradlew assembleDebug

    There! you’ll find the apk file in the following path:
    yourProject/android/app/build/outputs/apk/debug/app-debug.apk

    Same goes for IOS too.

    The metro screen only shows for debug builds. Make and run a Release build to run the app without the metro screen.

    To make a Release build for ios:

    To run release build in simulator:

    npx react-native run-ios --configuration Release

    To run release on phone:

    1. In xcode Product menu > scheme > edit scheme
    2. In sidebar click Run
    3. Select build configuration: Release
    4. Close dialog
    5. Run using Product > Run (same as when testing)
