CKQuery from private zone returns only first 100 CKRecords from in CloudKit

Question

Is there any limit to the result of a query to Cloudkit private default zone? I have no clue why I only receive first 100 records with the following query:<

Answer 1

The simplest example for Swift:

func fetchServices(completion: ErrorHandler? = nil) {

    var records = [CKRecord]()

    let query = CKQuery(recordType: "Service", predicate: NSPredicate(value: true))
    let queryOperation = CKQueryOperation(query: query)

    queryOperation.recordFetchedBlock = { record in
        records.append(record)
    }

    queryOperation.queryCompletionBlock = { cursor, error in
        self.fetchServices(with: cursor, error: error, records: records, completion: completion)
    }

    database.add(queryOperation)
}

private func fetchServices(with cursor: CKQueryCursor?, error: Swift.Error?, records: [CKRecord], completion: ErrorHandler? = nil) {

    var currentRecords = records

    if let cursor = cursor, error == nil {

        let queryOperation = CKQueryOperation(cursor: cursor)
        queryOperation.recordFetchedBlock = { record in
            currentRecords.append(record)
        }

        queryOperation.queryCompletionBlock = { cursor, error in
            self.fetchServices(with: cursor, error: error, records: currentRecords, completion: completion)
        }

        database.add(queryOperation)

    } else {
        parseAndSaveServices(with: records, completion: completion)
    }
}
