Upgrading version

0.61.5 => 0.63.0-rc.1

Description

We don't have no problem with the debug build, but when i run a release version in xcode, we obtain the following error:

• [[ ! -f /Users/lorenzoangelini/Library/Developer/Xcode/DerivedData/app-dlzjkrbjxmkvpvdoutbbotxjrzkw/Build/Products/Release-iphonesimulator/app.app/main.jsbundle ]]
• echo 'error: File /Users/lorenzoangelini/Library/Developer/Xcode/DerivedData/app-dlzjkrbjxmkvpvdoutbbotxjrzkw/Build/Products/Release-iphonesimulator/app.app/main.jsbundle does not exist. This must be a bug with'

before this error, it is showed this: Error: Unable to resolve module src/splashScreen/screen from src/_shared/routes/Navigator.tsx: src/splashScreen/screen could not be found within the project or in these directories: /Users/lorenzoangelini/project/app/app/node_modules/src/splashScreen

src/splashScreen/screen is an absolute path, that is not present into the node_modules. Why are it looking for them?

Reproducible demo

I upgraded and run a release build

We had a similar issue when upgrading to 0.63.0 (from 0.62.3), which turned out to be an issue with the js bundling script:

When running the command from the 'Bundle React Native code and images' script in <redacted>.xcodeproj/project.pbxproj manually (with dummy env vars: CONFIGURATION=Release CONFIGURATION_BUILD_DIR=$(pwd)/ConfBuildDir UNLOCALIZED_RESOURCES_FOLDER_PATH=Res ../node_modules/react-native/scripts/react-native-xcode.sh) it failed with an issue resolving @babel/runtime/helpers/interopRequireDefault, but it was trying to resolve from <project-dir>/ios/node_modules/@babel/runtime/helpers (note: nested in ios)

Patching node_modules/react-native/scripts/react-native-xcode.sh to cd .. before calling the bundling command fixed this issue:

--- node_modules/react-native/scripts/react-native-xcode.sh
+++ node_modules/react-native/scripts/react-native-xcode.sh
 
 BUNDLE_FILE="$DEST/main.jsbundle"
 
+cd ..
 "$NODE_BINARY" $NODE_ARGS "$CLI_PATH" $BUNDLE_COMMAND \
   $CONFIG_ARG \
   --entry-file "$ENTRY_FILE" \

ci also had a fatal error: module 'yoga' in AST file ... is not defined in any loaded module map file; maybe you need to load ... ?, but it still build correctly
