Apple iOS App Reject: Alamofire IPv6 not Supported

Question

Recently we submitted the new version of the app for review, it hasbeen rejected

Your app crashes on iPad and iPhone running iOS 9.3.5 connected to an IPv6 network

But i only used the Alamofire 3.4.1 for API Requests, with a domain name (not IP Address), and it is IPv6 Compatible Here is the results of the ipv6-test.com

Our ISPs not Providing IPv6 Only network, to check our app, We followed this procedure to setup the IPv6 in Mac, then it works here, after we submitted the build again, but it again rejected for the same reason

Can anybody suggest, how can we troubleshoot the issue/ is any thing wrong in my current environment

Answer 1

Try delete AAAA record of your domain.
So that your app can use NAT64 network to access your server other use ipv6 directly.

And it may help debug the issue.
