Warnings in Objective-C Pods

I have swift project. Warning Block implicitly retains 'self'; explicitly mention 'self' to indicate this is intended behavior appears when I use Objective-C pods:

• Bolts
• FBSDKCoreKit
• FBSDKLoginKit

Solution 1 (manual)

CLANG_WARN_OBJC_IMPLICIT_RETAIN_SELF = NO

Solution 2 (automatic)

Add to the end of your Podfile:

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