Question

When in debug mode app works fine. But during the release build it loads only the splash screen. But when I tick debug executable in release mode.The app is working fine. Please guide. Sorry for the format. Apple rejects my app

Guideline 2.1 - Performance - App Completeness

We discovered one or more bugs in your app when reviewed on iPad running iOS 12.4 on Wi-Fi.

Specifically, your app only launched to a splash screen with no other content available to the user.

Next Steps

To resolve this issue, please run your app on a device to identify any issues, then revise and resubmit your app for review.

Answer 1

Do clean of code by flutter clean

Install pods for iOS by cd ios then pod install .

Then make release build for iOS by flutter build ios --release .

Now you can open iOS project in xcode and only splash screen issue will be fixed.

Answer 2

You should be write following command in terminal(Android Studio/Visual Code)

rm -rf $HOME/Library/Developer/Xcode/DerivedData/*

# destroy entire flutter cache (will be redownloaded and rebuilt)
# rm -rf $HOME/Library/Flutter/bin/cache/*

# sometimes Flutter doesn't recompile the frameworks
rm -rf ios/Flutter/App.framework ios/Flutter/Flutter.framework

# remove the entire pub-cache
rm -rf ~/.pub-cache/*

# now, remove the build directory
rm -rf build

# now remove the .packages file
rm -f .packages

# now remove the plugins directory
rm -rf .flutter-plugins

pushd ios
pod deintegrate
rm -rf Pods Podfile.lock
rm -rf .symlinks/*
popd

flutter packages get

Answer 3

Same thing happened to me:

flutter clean
flutter build ios --release

Was all I needed (didn't need to do the pod install ).

Flutter app opens, but is stuck on splash-screen

Answer 4

You need to build initially from Android studio for iOS.

Initially clean your project - flutter clean

Then run below line in terminal of Android studio.

flutter build ios --release

Now, open XCode and clean project then make your archive. Your issue of stuck in Splash is resolved.
