Unable to get value of Parse.com column

Question

This is the craziest error I've encountered ever. I am trying to get the value from a column called nameRetailer in the Orders table, but it keeps getting nil.

Other columns of same String type are returning properly including the status column shown below.

What could lead to this? The spelling is certainly correct. Please help....

 let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd"
        let date = object?.objectForKey("dueDate") as! NSDate
        let strDate = dateFormatter.stringFromDate(date)

        cell.retailerName.text = object?.objectForKey("nameRetailer") as? String
        cell.orderDueDate.text = strDate
        cell.orderStatus.text = object?.objectForKey("status") as? String

When I tried to print the value of object?.objectForKey("nameRetailer"), it shows nil in console. In the parse data browser, column has data and was refreshed.

Update: Adding additional code:

The entire class code responsible for the table view:

class OrderViewController: PFQueryTableViewController {
    override func queryForTable() -> PFQuery {
        let query = PFQuery(className: "Orders")
        query.cachePolicy = .CacheElseNetwork
        query.orderByAscending("createdAt")
        return query
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell? {
        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! OrdersTableViewCell


        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd"
        let date = object?.objectForKey("dueDate") as! NSDate
        let strDate = dateFormatter.stringFromDate(date)

        cell.retailerName.text = object?.objectForKey("nameRetailer") as? String
        cell.orderDueDate.text = strDate
        cell.orderStatus.text = object?.objectForKey("status") as? String

        print(object)

        //let imageFile = object?.objectForKey("image") as PFFile
        //cell.cellImageView.image = UIImage(named:"placeholder") 
        //cell.cellImageView.file = imageFile
        //cell.cellImageView.loadInBackground()
        return cell
    }

    override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        if indexPath.row + 1 > self.objects?.count
        {
            return 44
        }

        let height = super.tableView(tableView, heightForRowAtIndexPath: indexPath)
        return height
    }


    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        if indexPath.row + 1 > self.objects?.count
        {
            self.loadNextPage()
            tableView.deselectRowAtIndexPath(indexPath, animated: true)
            self.performSegueWithIdentifier("showDetail", sender: self)
        }
    }

and here is the log snapshot of printing PFObject:

And here is the updated snapshots showing the two rows

Two rows having retailer name don't necessarily mean that whole column will have retailer name. Show us the object in Data browser, for which retailer name is returned nil. — NSNoob

There are only 2 rows and each record has multiple columns and one of them is nameRetailer shown above. How come status column showing and all others showing except this? — ksa_coder

When you print the PFObject, can you see retailers name in there? — NSNoob

Change query.cachePolicy = .CacheElseNetwork to query.cachePolicy = .NetworkOnly to force reload from server — jcaron

You have set your cache policy to start by looking up data in the local cache, which may be stale.

Change:

    query.cachePolicy = .CacheElseNetwork

to

    query.cachePolicy = .NetworkOnly // ignores cache on reading, but saves to cache

or

    query.cachePolicy = .IgnoreCache // no cache at all -- this is the default

(or other appropriate value based on your specific context and use case)
