Describe the bug

When working with "react-native": "0.80", + Expo, and npx expo prebuild --platform ios, it will fail the pod install, with following error message:

⚠️  Something went wrong running `pod install` in the `ios` directory.
Command `pod install` failed.
└─ Cause: Unable to find a specification for `RCT-Folly` depended upon by `AmplifyRTNWebBrowser`

You have either:
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

By reverting the RN version to 0.79.x, the pod install will work.

Expected behavior

The build should succeed and no errors in pod install

Reproduction steps

1. Use the version specified (RN >= 0.80.x)
2. pod install or npx expo prebuild --platform ios (for expo)

Hello @weijihuang , thanks for creating this issue. I will look into it and provide an update.

Hi @weijihuang

We've identified that this is related to React Native 0.80's new feature of using prebuilt dependencies, which is currently incompatible with our library's manual configuration of certain native dependencies.

There's a workaround provided in: dominicstop/react-native-ios-utilities#30 to disable the precompiled deps with adding these environment variables when running your app. I've tried and it works for me.

RCT_USE_PREBUILT_RNCORE=0 RCT_USE_RN_DEP=0 npx expo run:ios
# or for prebuild
RCT_USE_PREBUILT_RNCORE=0 RCT_USE_RN_DEP=0 npx expo prebuild --platform ios

In the meantime, we will work on making our library compatible with this latest feature and will provide an update when it's released.

@Simone319 Awesome! Came here to report and glad to see the Amplify team is already on it.

Amplify-rtn-core is addressed by this PR:

#14493

I also submitted a PR for rtn-web-browser and rtn-push-notifications:

#14553

[weijihuang]

Perfect! @ChristopherGabba I also see ERROR [Invariant Violation: TurboModuleRegistry.getEnforcing(...): 'PlatformConstants' could not be found. Verify that a module by this name is registered in the native binary.] when I run the app.
The error comes from aws-amplify/auth. Is this also related?

[Simone319]

@ChristopherGabba , thank you for your time and work on this PR! 🎉

Your contribution #14553 has been merged and will be included in the next release.

@weijihuang I don't think this is related, you may try cleaning your build directory?
