# Run Script Build Phase invoked by the "Brownfield Apple App" target after
# the standard "Embed Frameworks" phase.
#
# When the host RN project is RockApp, the dynamic BrownfieldLib.dylib
# produced by `rock package:ios` has @rpath load commands for
# React.framework and ReactNativeDependencies.framework. They must be
# embedded in the .app bundle or the app crashes on launch with
# "Library not loaded: @rpath/React.framework/React".
#
# `prepareXCFrameworks.js --appName RockApp` drops these xcframeworks into
# `package/`. For Vanilla / Expo flavors they are absent (React core is
# statically linked into BrownfieldLib), so this script is a no-op then.
