Not able to generate archive when using a Pod file

I managed to update to 0.46 rc2 from 0.43 today and everything was looking ok. Building a debug or production release was working. However when I tried to create an archive I ran in the following error:

Undefined symbols for architecture armv7:
  "_JSNoBytecodeFileFormatVersion", referenced from:
      +[RCTJavaScriptLoader loadBundleAtURL:onProgress:onComplete:] in libReact.a(RCTJavaScriptLoader.o)
      +[RCTJavaScriptLoader attemptSynchronousLoadOfBundleAtURL:runtimeBCVersion:sourceLength:error:] in libReact.a(RCTJavaScriptLoader.o)
  "facebook::react::parseTypeFromHeader(facebook::react::BundleHeader const&)", referenced from:

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

In my project I’m using react-native-maps and since I’m running google maps on iOS I have a podfile similar to this one: https://github.com/airbnb/react-native-maps/blob/master/example/ios/Podfile

It turns out that when I remove the following lines

  pod 'React', path: '../../node_modules/react-native', :subspecs => [
    'Core',
    'RCTActionSheet',
    'RCTAnimation',
    'RCTGeolocation',
    'RCTImage',
    'RCTLinkingIOS',
    'RCTNetwork',
    'RCTSettings',
    'RCTText',
    'RCTVibration',
    'RCTWebSocket'
  ]

the archive is being built correctly.

I’ve reproduced the error here: https://github.com/compojoom/rn46crash/tree/7c34cf696cf940e21566d73b7e76365fb6aab677

As you can see the podfile just has the pod Yoga and pod React lines.

To run the app, clone the repository and do yarn. Afterwards open the rn46crash.xcworkspace with XCode, assign a team to the project and build it. You should run in the specified error above.

I’m pasting this issue here and not in the react-native-maps repository as with RN 0.43 - I was able to create an archive with that pod configuration, that’s why I think that there is something wrong in the RN package.

• React Native version: 0.46 rc2
• Platform: ios
• Development Operating System: macOS
• Build tools: Xcode 8.3.3

It seems that adding BatchedBridge subspec resolves the issue. I found it out based on React.podspec file analysis. JSNoBytecodeFileFormatVersion is defined in JSCWrapper.cpp

@tuckg as mentioned above by adding BatchedBridge React subspec in Podfile

pod 'React', path: '../../node_modules/react-native', :subspecs => [
   ...,
   'BatchedBridge',
   ...
  ]
