I have exactly the same issue. Anybody has any ideas please? :-) I can try setting some merge policy but I am not sure if that is the best way as core data and CloudKit are supposed to do the 'last writer wins' by default so I don't understand what is going wrong.

I have the same problem in both simulators and my test device. Just submitted feedback as requested by Frameworks Engineer. Hope apple does something soon to solve this. StorekitTest is a really nice thing to have if not for this issue

Please? Anyone? 🙂

I am getting this too, on 12.01 Any ideas anyone?

Thanks again  @eskimo. MetricKit is also very interesting indeed. One more question about sysdiagnose log. The user has to take some manual steps to trigger the sysdiagnose log I guess. There is no automated way to send events to the cloud and look at it in a back end. I am guessing that is where MetricKit comes in. You can signPost critical bits of code and view them online. Is that right?

Thank you @eskimo, It appears to me that the sysdiagnose log is actually for investigating issues at the 'system wide' level and not at the app level (Such as monitoring the occurance of an app specific error) Is that correct?
