Build error with Xcode 12

[Francesco-Voto]

After Upgrading to Xcode 12 we got some problems to build the package.

Apparently the problem is the dependency inside the react-native-appboy-sdk.podspec

Changing s.dependency 'React' to s.dependency 'React-Core' seems to fix the problem.
Is this the right solution or you have some other fix?

Thank you

@Francesco-Voto can you post more information about the errors you're seeing?

Sure!

@Francesco-Voto I wasn't able to reproduce this using Xcode 12.4. I would recommend:

1. removing react-native-appboy-sdk from your node_modules and re-installing
2. removing your Pods directory and rerunning pod install

A few questions:

1. What version of react native are you on?
2. Do you see any warnings about autolinking?

Fwiw it looks like the missing symbol is from RCTEventEmitter, which is part of React. I would make sure wherever you're compiling React, that you aren't excluding architectures by overwriting or changing build settings

Switching from s.dependency 'React' to s.dependency 'React-Core' is needed to get off the Legacy Build system. cc @Bucimis

Thanks @jlo1 - I agree, that looks correct. I've filed an internal issue to investigate.

Hi @Francesco-Voto @jlo1,

This issue should be addressed in version 1.40.0 of the release from this attached PR. Feel free to open a new issue if you are still experiencing problems with that update or when testing on Xcode 13.

Thanks!
