cocoapods Debug hook for project with many schemes and configurations

Podfile

# targets with dependencies

# This is an alternative for manually specifying every configuration as :debug [link](http://guides.cocoapods.org/syntax/podfile.html#project). 
# Because of cocoapods by default uses :release type for all configurations but Debug
# we need to change every configuration, named <configuration_name>.Debug

# at the bottom of file
post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
          if config.name.include?('.Debug')
            config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES'
            config.build_settings['VALIDATE_PRODUCT'] = 'NO'
            config.build_settings['DEBUG_INFORMATION_FORMAT'] = 'DWARF'

Thanx for posting. As soon as I run pod install again I get warnings in Update Project Settings for the flags set!
