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:<

I have updated GuiSoySauce's code in Swift 4.2.

func cloudKitLoadRecords(result: @escaping (_ objects: [CKRecord]?, _ error: Error?) -> Void) {
    // predicate
    var predicate = NSPredicate(value: true)
    // query
    let cloudKitQuery = CKQuery(recordType: "recordType", predicate: predicate)

    // records to store
    var records = [CKRecord]()

    //operation basis
    let publicDatabase = CKContainer.defaultContainer().publicCloudDatabase

    // recurrent operations function
    var recurrentOperationsCounter = 101
    func recurrentOperations(cursor: CKQueryCursor?){
        let recurrentOperation = CKQueryOperation(cursor: cursor!)
        recurrentOperation.recordFetchedBlock = { (record:CKRecord!) -> Void in
            print("-> cloudKitLoadRecords - recurrentOperations - fetch \(recurrentOperationsCounter)")
            recurrentOperationsCounter += 1
            records.append(record)
        }
        recurrentOperation.queryCompletionBlock = { (cursor: CKQueryOperation.Cursor?, error: Error?) -> Void in
            if ((error) != nil) {
                print("-> cloudKitLoadRecords - recurrentOperations - error - \(String(describing: error))")
                result(nil, error)
            } else {
                if cursor != nil {
                    print("-> cloudKitLoadRecords - recurrentOperations - records \(records.count) - cursor \(cursor!.description)")
                    recurrentOperations(cursor: cursor!)
                } else {
                    print("-> cloudKitLoadRecords - recurrentOperations - records \(records.count) - cursor nil - done")
                    result(records, nil)
                }
            }
        }
        publicDatabase.add(recurrentOperation)
    }
    // initial operation
    var initialOperationCounter = 1
    let initialOperation = CKQueryOperation(query: cloudKitQuery)
    initialOperation.recordFetchedBlock = { (record:CKRecord!) -> Void in
        print("-> cloudKitLoadRecords - initialOperation - fetch \(initialOperationCounter)")
        initialOperationCounter += 1
        records.append(record)
    }
    initialOperation.queryCompletionBlock = { (cursor: CKQueryOperation.Cursor?, error: Error?) -> Void in
        if ((error) != nil) {
            print("-> cloudKitLoadRecords - initialOperation - error - \(String(describing: error))")
            result(nil, error)
        } else {
            if cursor != nil {
                print("-> cloudKitLoadRecords - initialOperation - records \(records.count) - cursor \(cursor!.description)")
                recurrentOperations(cursor: cursor!)
            } else {
                print("-> cloudKitLoadRecords - initialOperation - records \(records.count) - cursor nil - done")
                result(records, nil)
            }
        }
    }
    publicDatabase.add(initialOperation)
}

Usage

cloudKitLoadRecords() { (records, error) -> Void in
    if let error = error {
        // do something
    } else {
        if let records = records {
            // do something
        } else {
            // do something
        }
    }
}
