Deleted CloudKit records Reappear

Question

I\'m building an iOS application using CloudKit.

It should allow a user to add, edit and delete Products in the cloud. The user can organize these in Folder

This might happen because the dashboard trace below suggests Apple use the Tombstone technique for replicating deletes across a distributed database. One of the nodes might have a bug or an old software version and is syncing the tombstone false field back across the system, causing the record to undelete itself. Or maybe something your code is doing is accidentally bringing these deleted records back to life? A workaround would be to use your own soft-delete boolean field and see how that behaves.

[{
    "results": [{
        "tombstone": false
        "id": "NewItem",
        "etag": "ibgs5bpj",
        "recordType": "Items",
        "fields": {
            "name": "Malc",
            "location": {
                "latitude": 38.0,
                "longitude": -122.0
            }
        },
        "conflictLosersEtags": [],
        "created": {
            "timestamp": 1435514295943,
            "user": "_0ac573ae502ca7ca9d763a84b27bc42a",
            "device": "_2"
        },
        "modified": {
            "timestamp": 1435514295943,
            "user": "_0ac573ae502ca7ca9d763a84b27bc42a",
            "device": "_2"
        }
    },
    ...

As for the record counts, yes mine are inaccurate too.

Apple replied to a bug report that I have filed that this issue should be solved with iOS 9. So far that seems to be right as this issue hasn't occured again, but please let me know if this is still bothering someone.
