CocoaPod 1.9.3: How to resolve the APPLICATION_EXTENSION_API_ONLY warning?

I'm stuck with this and hope someone can help. How can I remove/resolve these warnings, please?

def shared_pods
  pod 'SSZipArchive'
  pod 'KeychainAccess'
  pod 'SwiftyBeaver'
end

target 'myApp' do
  platform :ios, '11.0'
  use_frameworks!
  shared_pods

  pod 'IQKeyboardManagerSwift'
  pod 'Firebase/Analytics'
  pod 'Firebase/Crashlytics'
  pod 'FacebookSDK/CoreKit'
  pod 'FacebookSDK/ShareKit'
  pod 'Google-Mobile-Ads-SDK'
  pod 'GoogleMobileAdsMediationAdColony'
  pod 'GoogleMobileAdsMediationIronSource'
  pod 'OpenVPNAdapter', :git => 'https://github.com/ss-abramchuk/OpenVPNAdapter.git', :tag => '0.7.0'
  target 'myAppTests' do
    inherit! :search_paths
  end

  target 'myAppUITests' do
  end

  target 'tunnel-ios' do
    pod 'OpenVPNAdapter', :git => 'https://github.com/ss-abramchuk/OpenVPNAdapter.git', :tag => '0.7.0'
  end
end
post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'No'
     end
  end
end

I'm getting these warnings:

    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.
