IPv6 network support

[Wenxu_Zhang]

Hello, Sir
I created an iOS application to use Kii Cloud as a MBaas.
I submitted my application to App Store, but rejected as
crashed both on iPhone and iPad, running iOS 10.2.1 connected to an IPv6 network.
I managed to set up a local IPv6 Wi-Fi network as instructed by following:
https://developer.apple.com/library/content/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/UnderstandingandPreparingfortheIPv6Transition/UnderstandingandPreparingfortheIPv6Transition.html
The application runs well.
The crash log sent by Apple team indicates that the following statement has something wrong,
let clause1 = KiiClause.equals(Ebbinghaus_keyName, value: app.myID!)
where both Ebbinghaus_keyName and app.myID are just pure string.
Any advice is appreciated.
Thanks in advance.

Hi Wenxu_Zhang,
Thanks for using KiiCloud.
To investigate the crash, would you mind to send the crashlog?

Hi, Mr. Riza
Thanks for your reply.
I will attach crash log and dSYM file.

let clause1 = KiiClause.equals(Ebbinghaus_keyName, value: app.myID!)

The problem is unrelated to iPV6, i can assure because i have tested on the ipv6 and the method is an instantiation which does not connect to internet or doing networking task.

Based on your crashlog, my guess either Ebbinghaus_keyName or app.myID is nil at runtime.

Exception Type:  EXC_BREAKPOINT (SIGTRAP)
Exception Codes: 0x0000000000000001, 0x000000010004a974
Termination Signal: Trace/BPT trap: 5
Termination Reason: Namespace SIGNAL, Code 0x5
Terminating Process: exc handler [0]
Triggered by Thread:  0

Anyway it is very important to know that what is SIGTRAP means. It is basically a run-time exception not an error. So if you cannot really find the issue you have to check that if there are any places which can course an exception. (specially with Swift optional types)

Hi, Mr. Riza
Thank you very much.
I will check if something is wrong with myID.
Thanks again.
