CloudKit data table rows gone

I have a simple app that stores authors and books I’ve read on CloudKit. Used the app last Saturday and data returned. This morning it wouldn’t return rows… logged into CloudKit dashboard and all the data rows are gone! Table definition are in tact. Have not been in the dashboard or made app changes. Opened a question with Apple. Looking for thoughts on a root cause for a data loss.

@berberich Do you still have issues with this?

if you are still facing this problem and have not found a fix, then you will have to share some code where you write the data to CloudKit, it seems that some part of your code has resulted in deleting the data but now writing the updated one.
