# react_native_pax_pods.rb
# Fixes symbol conflicts between SSZipArchive and libPOSLinkAdmin.a.
# Both export the same unz*/zip* symbols as globals; the fix prefixes
# SSZipArchive's copies so the linker sees distinct names.
#
# Usage — add to your app's Podfile:
#
#   require_relative '../node_modules/@haroldtran/react-native-pax/react_native_pax_pods'
#
# Then call inside your post_install block:
#
#   post_install do |installer|
#     react_native_pax_pods(installer)
#     # ... other post_install steps
#   end
