SWIFT/CloudKit - Updating a record and saving it back to container

I'm having a problem updating CloudKit records. What I want to achieve is the ability to allow users to vote for a book by clicking a tableview row. This tableview is currently filled using records from Cloud data. I'm stuck when I want to retrieve a record (ie. the selected tableview row), and increase its voteCount column by 1, then save it back to the cloud and reload the data in the tableview.

Currently I am retrieving records by:

    booksIncludedInVote = []
    let cloudContainer = CKContainer.defaultContainer()
    let publicDatabase =CKContainer.defaultContainer().publicCloudDatabase

    let predicate = NSPredicate(value: true)
    let query = CKQuery(recordType: "Book", predicate: predicate)
    let queryOperation = CKQueryOperation(query: query)
    queryOperation.desiredKeys = ["name", "author", "image", "description", "voteCount"]
    queryOperation.queuePriority = .VeryHigh
    queryOperation.resultsLimit = 50
    queryOperation.recordFetchedBlock = { (record:CKRecord!) -> Void in
    if let restaurantRecord = record {
      self.booksIncludedInVote.append(restaurantRecord)
    }

Can you help me update a particular record and then send it back up to the cloud?

You would also need code like this:

    operation.queryCompletionBlock = { cursor, error in
            self.tableView.ReloadData()
        }
    publicDatabase.addOperation(operation)
}

func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
     var record = self.booksIncludedInVote[indexPath.row]
     // now increment the voteCount value in that record and save it using 
     publicDatabase.saveRecord(theRecord, completionHandler: { record, error in
     }
}
