CloudKit: Fetch all records with a certain record type?

Question

I have currently got CloudKit set up in my app so that I am adding a new record using the help of the following code below,

CKRecordID *recordID         


        

Answer 1

The followig function will return ALL records for requested record type:

let database = CKContainer(identifier: "container_here").privateCloudDatabase
typealias RecordsErrorHandler = ([CKRecord], Swift.Error?) -> Void

func fetchRecords(forType type: String, completion: RecordsErrorHandler? = nil) {

    var records = [CKRecord]()

    let query = CKQuery(recordType: type, predicate: NSPredicate(value: true))
    let queryOperation = CKQueryOperation(query: query)
    queryOperation.zoneID = CloudAssistant.shared.zone.zoneID

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

    queryOperation.queryCompletionBlock = { cursor, error in

        self.fetchRecords(with: cursor, error: error, records: records) { records in
            completion?(records, nil)
        }
    }

    database.add(queryOperation)
}

private func fetchRecords(with cursor: CKQueryCursor?, error: Swift.Error?, records: [CKRecord], completion: RecordsHandler?) {

    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.fetchRecords(with: cursor, error: error, records: currentRecords, completion: completion)
        }

        database.add(queryOperation)

    } else {
        completion?(records)
    }
}
