create UITableViewCell from uicollectionView choice - ios

Question

I'm actually doing an app which loads contents to a UICollectionView as the user selects 1 it should create a UITableViewCell and add it to an UITableView on the right but I keep getting errors
In the ViewDidLoad I register the Nib (where cart #IBOutlet var cart: UITableView? and is connected to Storyboard)
cart!.registerNib(UINib(nibName: "cartCell", bundle: nil), forCellReuseIdentifier: "Cell")
When the cell is selected I add the object to an array and refresh the table
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
if indexPath.row < serviceList.count {
let service:Service = serviceList[indexPath.row]
cartOrder.append(service)
dispatch_async(dispatch_get_main_queue()){
self.cart!.reloadData()
}
}
}
But when the table is filling its content I get an error at the declaration of cell
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! cartCell
let serv = cartOrder[indexPath.row]
cell.lblName.text = serv.name
cell.lblDescription.text = serv.description
cell.imgService.image = UIImage(named: "star")
return cell
}
The error Im getting is
2016-02-19 16:41:33.375 trackMyDevice_1.0[43188:5851609] ***
Terminating app due to uncaught exception 'NSUnknownKeyException',
reason: '[<NSObject 0x7fe645009320> setValue:forUndefinedKey:]:
this class is not key value coding-compliant for the key imgService.'
Any help is well appreciated

Answer 1

I register the Nib
So you have a nib called cartCell.xib, is that right? And that's what you are registering here:
cart!.registerNib(UINib(nibName: "cartCell", bundle: nil),
forCellReuseIdentifier: "Cell")
Later you load that nib to get a cell, by saying this:
let cell = tableView.dequeueReusableCellWithIdentifier("Cell",
forIndexPath: indexPath) as! cartCell
Now, that line makes an explicit claim that the cell loaded from the nib will be a cartCell. But the problem is that the top-level object in that nib, cartCell.xib, is in fact not a cartCell. It isn't any kind of UITableViewCell. It is an NSObject! And thus, you crash with a complaint that this thing is an NSObject:
<NSObject 0x7fe645009320> ... this class is not key value coding-compliant for the key imgService
