I want to target iOS 15 and I get deprecation warnings in some CloudKit properties. I was using modifyRecordsCompletionBlock on CKModifyRecordsOperation and now I get:

'modifyRecordsCompletionBlock' was deprecated in iOS 15.0: Use modifyRecordsResultBlock instead

However with modifyRecordsCompletionBlock I'd get an array of the successfully modified records as input for the block which I'd in turn use for updating my local DB, whereas the input for modifyRecordsResultBlock is Result<Void, Error>.

Basically I'm being told to use a different closure where I get no data and I don't know how to complete my local DB updates.

Any ideas?

Supply a perRecordSaveBlock and perRecordDeleteBlock within that operation and maintain the cumulative results there, leaving the modifyRecordsResultBlock free to describe the operation as a whole.

Watch this video and it will describe the enhancements made this year in full detail for the new resultBlock closures (and new async methods too!) Having migrated over to the new API, it is really a nice update though some of my closures were gnarly (doing atomic processing with records that referenced each other as an example).

I think we have to keep using modifyRecordsCompletionBlock because modifyRecordsResultBlock doesn't error on server record changed, it erroneously reports success. As of Xcode 14b1 iOS 16b1. See this post for more info.
