UPDATE notification stopped working. What workaround do you have, until Apple figures out something?
CKFetchNotificationChangesOperation sometimes does not return UPDATE, DELETE notifications CloudKit push notifications on record update stopped working https://forums.developer.apple.com/thread/7288
My quick fix, that in every minute, and when user triggers UIRefreshControl, then I downloading all the records that were modified since the last update. It works. But I have a better idea in my mind, curious, what do you think. Any drawbacks.
I am thinking adding a Change table to the database. It will have a recordName, recordType, changeType fields. changeType could have insert, update, delete string values. (or int enumerations accordingly)
And I would create and observe with CKSubscription only the Change table. Always when a record is create, updated, deleted in a custom table, I would do two things, do that action and as a second action I would make a 'log entry' into the Change table. Because it is an Insert operation in Change, and insert notification seems to work, all the device would get notified. They could download the refered record.
Do you see any drawbacks?
