[React-Native]Workaround for Xcode 12 Linking Errors

Lost React.framework reference for some Frameworks which depends on React.framework.

Add to the end of Podfile

post_install do |installer|
  puts("### Workaround for Xcode 12 and Auto-Linking")
  installer.pods_project.targets.each do |target|
    if ['RNCAsyncStorage', 'RNVectorIcons', 'RNLocalize', 'React-RCTText', 'react-native-mapbox-gl', 'RNPermissions', 'RNReanimated', 'RNScreens', 'RNShare', 'react-native-netinfo', 'RNSVG', 'RNCisco', 'RNCiscoContribution', 'RNCiscoNotification', 'react-native-camera', 'react-native-safe-area-context', 'react-native-segmented-control', 'RNCPicker'].include?(target.name) #list all affected target in the array
      target.build_phases.each do |build_phases|
        if build_phases.display_name == 'Frameworks'
          file_ref = installer.pods_project.new(Xcodeproj::Project::Object::PBXFileReference)
          file_ref.path = 'React.framework'
          file_ref.source_tree = 'BUILT_PRODUCTS_DIR'
          build_phases.add_file_reference(file_ref)
          puts("### #{target.name} ==> Adding React.framework reference")
        end
      end
    end
  end
end

Bonjour service not working on iOS 14

Root Cause: Should add support for local network privacy permissions in iOS 14

https://developer.apple.com/forums/thread/653316

https://developer.apple.com/videos/play/wwdc2020/10110/

Fix: Add permissions to plist

    <key>NSLocalNetworkUsageDescription</key>
    <string>Looking for local devices with tcp Bonjour services</string>
    <key>NSBonjourServices</key>
    <array>
        <string>_YOUR_LOCAL_SERVICE._tcp</string>
    </array>
