A post install script for CocoaPods that changes the bundle identifier of all pods to the one specified.

cocoapods-bundle-id

post_install do |installer|
  
  installer.project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.name == 'BREnterprise'
        config.build_settings['CODE_SIGN_IDENTITY[sdk=iphoneos*]'] = 'iPhone Distribution: The Carter Group LLC'
        config.build_settings['PROVISIONING_PROFILE'] = '${BR_ENTERPRISE_PROVISIONING_PROFILE}'
      end
    end
  end
  
  # change bundle id of each pod to 'com.bottlerocketapps.*'
  bundle_id = 'com.bottlerocketapps'

  directory = installer.config.project_pods_root + 'Target Support Files/'
  Dir.foreach(directory) do |path|

    full_path = directory + path
    if File.directory?(full_path)

      info_plist_path = full_path + 'Info.plist'
      if File.exist?(info_plist_path)

        text = File.read(info_plist_path)
        new_contents = text.gsub('org.cocoapods', bundle_id)
        File.open(info_plist_path, "w") {|file| file.puts new_contents }
      end
    end
  end
end

Extremely helpful. Since I wanted a different bundle_id per POD framework I changed the code to:

post_install do |installer|
    bundle_id = 'nl.evict.'
    directory = installer.config.project_pods_root + 'Target Support Files/'
    Dir.foreach(directory) do |path|
        full_path = directory + path
        if File.directory?(full_path)
            info_plist_path = full_path + 'Info.plist'
            if File.exist?(info_plist_path)                
                text = File.read(info_plist_path)
                new_contents = text.gsub('${PRODUCT_BUNDLE_IDENTIFIER}', bundle_id + path)
                File.open(info_plist_path, "w") {|file| file.puts new_contents }
            end
        end
    end
end

Thanks for sharing.
