My team didn't want to use cocoapods 1.10 before it's released, and didn't want to re-edit the Pods project's build settings every time a pod install regenerates it. This Podfile post_install step did the trick, credit to Léo-Paul JULIE:

post_install do |installer|
  installer.pods_project.build_configurations.each do |config|
      config.build_settings['CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER'] = 'NO'
    end
end

Edit: As snakeoil points out below, you can also silence annoying warnings about irrelevant iOS versions which you are not supporting. But that setting should probably be edited for each target's configuration's build settings, so in a nested loop. All together, I'm going with something like this for now:

post_install do |installer|
  installer.pods_project.build_configurations.each do |config|
    # Can be removed when moving to cocoapods 1.10
    config.build_settings['CLANG_WARN_QUOTED_INCLUDE_IN_FRAMEWORK_HEADER'] = 'NO'
  end
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      # Inherit the deployment target defined in this Podfile instead, e.g. platform :ios, '11.0' at the top of this file
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end
