Sample Podfile for silencing warnings for CocoaPods dependencies

Podfile

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target '%TargetName%' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for %TargetName%
  # pod 'FBSDKCoreKit'
end

# Silence warnings by turning them off from the Build Settings
