> "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."

In effect this is not true, as a developer without the time to fully implement IPv6-only networking I've been slapped with this rule in the app store review guidelines for non-complying apps numerous times. Just submit a new review and you'll get another reviewer who does not check this and you'll pass.

The rule they cite is also that you have to be able to support IPv6 for iPad-apps, not iPhone apps...

So even if it's the rule, I think that in reality it's not going to be true for all the users apps.

A rule that is not enforced properly does not invalidate the rule. Do you want to rely for your app to get approved to get a non-enforcing reviewer forever in the future? Also think of your customers on networks like TMo.

What prevents you from supporting IPv6-only networking? HTTP libraries support it out of the box. If you use sockets, just update them to use PF_INET6 and it'll be backward-compatible with IPv4 through IPv4-embedded IPv6 addresses.
