CKQueryOperation queryCompletionBlock only runs 3 times

Question

I\'m trying to download a batch of records from my iCloud public database using CloudKit and the cursor. The code works fine for the first 3 executions, regardless of how t

Answer 1

This could be another approach (already updated to Swift 3).

It does not stops after third iteration, but continues until the end

var queryOp = CKQueryOperation(query: query)
queryOp.recordFetchedBlock = self.fetchedARecord
queryOp.resultsLimit = 5
queryOp.queryCompletionBlock = { [weak self] (cursor : CKQueryCursor?, error : Error?) -> Void in
    print("comp block called with \(cursor) \(error)")

    if cursor != nil {
        let nextOp = CKQueryOperation(cursor: cursor!)
        nextOp.recordFetchedBlock = self!.fetchedARecord
        nextOp.queryCompletionBlock = queryOp.queryCompletionBlock
        nextOp.resultsLimit = queryOp.resultsLimit

        //this is VERY important
        queryOp = nextOp

        self!.publicDB.add(queryOp)
        print("added next fetch")
    }

}

self.publicDB.add(queryOp)

I successfully use it to retrieve hundreds of records from CloudKit
