EAS iOS build fails with Fastlane error: "error extracting version from module interface"

Expo Application Services (EAS)
1
  • Managed Workflow
  • eas-cli version is 0.60.0

Goal: embed third-party native library as npm package to a managed Expo project.
What I have: the library provided by vendor as a .xcframework for iOS (Swift) and .aab file for Android.
What I did:

  • generated a template for custom React Native library using npx create-react-native-library command.
  • added .aab and .xcframework files to appropriate folders.
  • provided implementation in Java and Swift for both platforms.
  • built library locally.
  • prior to publish my RN package to a private GH repo I tested library in example app which was generated by create-react-native-library, to ensure that everything works right.
  • example app works as expected.
  • published RN package to a repo and installed it into my Expo project.
  • STUCK ON THIS STEP: I try to build custom dev client using eas build command. And the build fails.

Do anyone know what does this mean and how to fix this?

More context:

  • I use latest image for iOS in eas.json file with XCode 13.4 and Swift 5.6.1
  • example RN app compiles and works as expected with my custom library. On my local Mac I use XCode 13.4.1 and Swift 5.6.1 as well.
