Intercom Bug Reproduction (Expo + React Native)

This repository is a minimal Expo project created to reproduce a bug with @intercom/intercom-react-native versions 9.. when used with the old React Native architecture.

It was reported in this Intercom Community question: https://community.intercom.com/mobile-sdks-24/intercom-react-native-does-not-compile-for-expo-during-build-when-combined-with-other-packages-12960

This is NOT present when using version 8.8.0 of the React Native Intercom module, and thus introduced with the upgrade to the new package.

🧱 Stack

• Expo SDK 52
• React Native (old architecture)
• @intercom/intercom-react-native
• @usercentrics/react-native-sdk
• config-plugin-react-native-intercom
• expo-build-properties

⚙️ Setup

1. Install dependencies:

   yarn install

   Ensure Node version ≥ 20.19.4 (required by Metro):

nvm install 20.19.4 && nvm use 20.19.4

Prebuild native projects:

npx expo prebuild --clean

run:

yarn ios

assert that you can not build due to below issue.

Bug description:

I’ve encountered a reproducible build issue on iOS when combining Intercom React Native v9.2.0 with @usercentrics/react-native-sdk.

✅ Works fine

• Intercom v9.2.0 alone → builds and runs on iOS.
• Usercentrics alone → builds and runs on iOS.

❌ Breaks when combined When both dependencies are installed, the iOS build fails during compilation with errors like:
