CloudKit - partialFailure and limitExceeded

Question

Summary

In CloudKitwould like to know everything possible CKError.Codefor .partialFailure.

Currently, I only process CKError.Codefor partial failure.

Assumptions:

• .serverRecordChanged// Applies only when saving records
• .zoneNotFound// applicable only when selecting zones
• .unknownItem// Applies only when retrieving elements
• .batchRequestFailed// Applies only when saving records in the user zone

---

• Technically, partialFailure can cause any CKError, but logically partialFailure is a failure at the position level, and not at the working level, therefore partialFailureit will not contain work-level errors, such as networkUnavailable/ badContainer/ badDatabase.
• Pay attention to how it is processed partialFailure- https://developer.apple.com/library/content/samplecode/CloudKitShare/Introduction/Intro.html (Search handlePartialError) -

Questions:

• In the case partialFailure, as indicated above, the only possible error codes?

• Are error serverRecordChanged, zoneNotFound, unknownItemis only possible as part of the error partialFailure? (Would be a mistake, the returned completion handler, does not directly contain serverRecordChanged, zoneNotFound, unknownItembut only partialFailureerror can keep them?)

• My comments are regarding when each of the above errors is correct? (Applicable only when ...)

• Error limitExceededfor operations CKFetchand CKModifyor is it only applicable for operations CKModify?
