IPv6 App Store Rejection

Question

Our update has been rejected twice today for ipv6 network connectivity issues. Our networking code has not changed between the previous release and this current release.

Answer 1

my app is rejected two times on app store. They give a error to twitter login on iphone having os 11.4. The main issue we have because of callback url of twitter, which is not set on developer account of twitter. when i set callback url on developer account of twitter. It solves my issue. When we dont set callback url on developer accountof twitter that time twitter login is successfull when device having twitter app. but in case of absence of twitter app on device gives forbidden error 403.

So Setting callback url overcomes my problem and app is accepted.

Thank you

Answer 2

we met the same problem。 Our App has been rejected serval times for ipv6 reason . But We have been test in the ipv6 network which configed as APPLE's Offical Document: https://developer.apple.com/library/mac/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/UnderstandingandPreparingfortheIPv6Transition/UnderstandingandPreparingfortheIPv6Transition.html#//apple_ref/doc/uid/TP40010220-CH213-SW1

Answer 3

We ran into similar situation. Our app was rejected due to connectivity problems in IPv6 networks. Also our servers are using AWS.

I've performed Test for IPv6 DNS64/NAT64 without any issue on my side, and we decide to submit an appeal to this rejection.

We explained that the test on our side was finished with success and that we are using AWS infrastructure.

After two more days the app was again reviewed and accepted

Answer 4

I've performed Test for IPv6 DNS64/NAT64 without any issue as prescribed by Apple documentation

however, we are unable to reproduce the issue (Crash). We successful install app in our devices without crashes.

• We took a video of this total testing process (which includes showing connectivity, downloading from testflight, NAT64 network connection , app operations)
• and appeal for rejection with the video file

Finally, app store APPROVED my app

Answer 5

I ran into the same app rejection when using the Facebook SDK. If you are using the Facebook SDK for login, it is incredibly important to logout the user when ending a session. Otherwise you will face similar app rejections in the future. I have included the code below to help those who may be experiencing similar issues.

let loginManager = FBSDKLoginManager()
loginManager.logOut()

Answer 6

We ran into this same problem, and it turned out while we had setup an AAAA record for IPv6, since we didn't actually have IPv6 support (we're also using Route53), it borked everything. Removing the AAAA record fixed the issue.

I've filed a radar about the discrepancy between the documentation for testing and the setup App Review is using - we were only able to diagnose it because our CTO was at WWDC and was able to connect to their network, which is not exactly a situation we can reproduce regularly.
