Every time is use a different simulator or a physical device, I have to generate new example data.

The debug log shows many errors, for example "Skipping migration", "Failed to modify some record zones", "Failed to set up CloudKit integration" and "Failed to sync user keys".

Has someone else this problem or an solution to this? Google didn't help.

Hello,

I seem to be having the same issue. Were you able to solve this ?

hi, i have started getting this error recently testing my app in simulator, do you remeber how did you solve it or was it temporary issue ?

Hello I had the same problem using real devices, iPhone, iPad and Mac. Reseting the CloudKit container environment solved it. Open the CloudKit Console, navigate to the CloudKit Database, select your Ultimate Portfolio container. On the button left you find the link “Reset Environment” Cheers Aendu
