DEBUG preprocessor macro not defined for CocoaPods targets

Question

I\'m having issues with a pod called DCIntrospect-ARC which should only work in DEBUG mode. It checks if the DEBUG macro is defined before running. However, it is not define

Thanks to John I completed my custom Podfile script, which also changes the optimization level to zero and enables assertions.

I've got multiple debug configurations (for ACC and PROD), so I needed to update several properties for debugging purposes.

post_install do |installer|
  installer.pods_project.build_configurations.each do |config|
    if config.name.include?("Debug")
      # Set optimization level for project
      config.build_settings['GCC_OPTIMIZATION_LEVEL'] = '0'

      # Add DEBUG to custom configurations containing 'Debug'
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
      if !config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'].include? 'DEBUG=1'
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'DEBUG=1'
      end
    end
  end

  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.name.include?("Debug")
        # Set optimization level for target
        config.build_settings['GCC_OPTIMIZATION_LEVEL'] = '0'
        # Add DEBUG to custom configurations containing 'Debug'
        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
        if !config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'].include? 'DEBUG=1'
          config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'DEBUG=1'
        end
        # Enable assertions for target
        config.build_settings['ENABLE_NS_ASSERTIONS'] = 'YES'

        config.build_settings['OTHER_CFLAGS'] ||= ['$(inherited)']
        if config.build_settings['OTHER_CFLAGS'].include? '-DNS_BLOCK_ASSERTIONS=1'
          config.build_settings['OTHER_CFLAGS'].delete('-DNS_BLOCK_ASSERTIONS=1')
        end
      end
    end
  end
end
