At WWDC 2015 Apple announced the transition to IPv6-only network services in iOS 9. Starting June 1, 2016 all apps submitted to the App Store must support IPv6-only networking.
My Delphi IOS App have a IPv4 IP, im using a TDSRestConnection now in the Host property i set 2112:d8ac:64c4::d8bc:64c4 and say "error is socket error11004" if i use the IPv4 format all is fine.
How i make my IOS app use IPv6.
I'm Using XE8, Rest DataSnap Server
