Question

Iphone app rejected because of the the reason that “We discovered one or more bugs in your app when reviewed on iPad and iPhone running iOS 10.0 on Wi-Fi connected to an IPv6 network.” Anyone can help to solve it?

You need to debug your app in a NAT64 Network. (You can create it by using your macOS.)

And Apple support article is following: https://developer.apple.com/library/content/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/UnderstandingandPreparingfortheIPv6Transition/UnderstandingandPreparingfortheIPv6Transition.html
