[iOS] runtimeVersion from Expo.plist ignored

Summary

I know that the issue is not specific to the eas-cli itself, but rather to the build service, however, I still thought it fits best here (please correct me otherwise). The official documentation states that for a runtime version in a bare project you have to set EXUpdatesRuntimeVersion in the Expo.plist (see here). I did this, and when building the project locally I can see that when inspecting the built ipa file that the contained Expo.plist contains the runtime version (obviously). However, when building the app with eas build this configuration is ignored. The resulting ipa file’s Expo.plist doesn’t contain the runtimeVersion.

To me, it feels like Runtime Versions are not supported yet with eas build?

Managed or bare?

Bare

Environment

EAS CLI 0.40.0 environment info:
    System:
      OS: macOS 12.0.1
      Shell: 5.8 - /bin/zsh
    Binaries:
      Node: 14.17.6 - ~/.nvm/versions/node/v14.17.6/bin/node

    Project workflow: generic

Error output

There is no error output by the CLI itself

Reproducible demo or steps to reproduce from a blank project

1. Create a bare expo project (dev client)
2. Set a EXUpdatesRuntimeVersion key value in the Expo.plist
3. Build the iOS app with eas
4. See how your set runtime version has been ignored in the final build artifact

Happy you were able to resolve this @hannojg, but @dsokal is right that this is weird behavior, thanks for bringing it to our attention!

Yes, when setting the runtime version env when calling eas build everything works as expected. Closing this for now, thx!
