[iOS SDK] Apple's requirements to support IPv6-only networks
Apple says,
"Starting June 1, 2016 all apps submitted to the App Store must support IPv6-only networking."
"If your app uses IPv4-specific APIs or hard-coded IP addresses, you will need to make some changes."

Is iOS SDK itself free from this concern?
