Crash on Apple Review - iOS

Question

I had submit application several time to review. But every time Apple tester said the application crash. I test on my application in environment IPV4. Totally no crash, but Apple tester said crash when launch as below. It's the problem about IPV6? I can't test in environment IPV6.

Thank you for your resubmission. We were unable to review your app as it crashed on launch. We have attached detailed crash logs to help troubleshoot this issue.

Steps to reproduce:

1) Start the app on a device 2) the app attempts to launch and crashes

Next Steps

Please revise your app and test it on a device while connected to an IPv6 network (all apps must support IPv6) to ensure it will launch without crashing.

Answer 1

You can use your mac to share an IPV6 network.

1. Open System Preferences
2. Option-click on the Sharing preference pane
3. Option-click on Internet Sharing
4. A Create IPv6 Only Network checkbox will appear
5. Check Create IPv6 Only Network (this may also be labeled Create NAT64 Network)
6. Select the interface to share out over (usually this will be WiFi, to allow iOS devices to connect.)
7. Check the box to start internet sharing
