[v10.0.0-beta.12] [iOS] ld: symbol(s) not found for architecture x86_64

See original GitHub issue

Goals

Build a React Native app using v10.0.0-beta.12.

Expected Results

iOS app builds and runs successfully.

Actual Results

Build fails with linker errors (undefined symbols) in libRealmJS.a. I have tried cleaning Xcode build directories, removing node_modules/, removing ios/Pods/, and reinstalling.

Note: Android builds and runs fine, so this is only an iOS issue.

Steps to Reproduce

Repro case here: https://github.com/ioveracker/mongodb-realm-react-native-playground/tree/realm-v10.0.0-beta.12

Install packages with yarn.
Install iOS dependencies with cd ios && pod install (or use yarn setup:ios if you have rbenv and want to lock in the same ruby / bundler / cocoapods versions).
Attempt to build and run the iOS app with yarn ios.
