Removing Unused Localizations

... If you are using CocoaPods, you may want to remove unwanted localizations using the pre install script below. Modify the supported_locales array to match your supported locales and paste it into your Podfile.

Note the all lowercase

    # Pods for MyApp-iOS

    # Remove unused languages from Pods
    pre_install do |installer|
        supported_locales = ['base', 'en', 'english']
        delete_unsupported_locales(installer.sandbox.root, supported_locales)
    end
end

def delete_unsupported_locales(root, supported_locales)
    Dir.glob(File.join(root, '**', '*.lproj')).each do |bundle|
        if (!supported_locales.include?(File.basename(bundle, ".lproj").downcase))
            puts "Removing #{bundle}"
            FileUtils.rm_rf(bundle)
        end
    end
