Summary:
Within the `hermes-engine.podspec` contained in the RN repo (at `react-native/main/sdks/hermes-engine/`), there's a bit of logic that triggers `./utils/build-ios-framework.sh` and `./utils/build-mac-framework.sh` .
The issue is that we all thought that that `./utils/build-ios-framework.sh` would invoke the React native version of the scripts (since the podspec file lives right next to the `utils` folder) but, in reality, it doesn't. It just so happens that the Hermes repo has a root level `utils` folder which is (you guessed it) where the Hermes variation of those build scripts live.
So, when running the pod install command in a react-native project (build from source), it will go and download the hermes source code (since the `source[:git]` gets set) but then it will use the **hermes** variation of the `build-*.sh` scripts.
