I am getting the following error when I tried to load NSCollectionviewItem in: collectionView(_ collectionView: NSCollectionView, itemForRepresentedObjectAt indexPath: IndexPath)

Error :

could not instantiate an NSViewController for a nib in the "CollectionViewCell" bundle because the bundle has not been loaded

I am loading CollectionViewItem from xib

Written following code in viewDidLoad

let nib = NSNib(nibNamed: "CollectionViewCell", bundle: nil)
    if #available(OSX 10.11, *) {
        self.collectionView.register(nib, forItemWithIdentifier: "CollectionViewCell")
    }



func collectionView(_ collectionView: NSCollectionView, itemForRepresentedObjectAt indexPath: IndexPath) -> NSCollectionViewItem {

        if #available(OSX 10.11, *) {

            let item = collectionView.makeItem(withIdentifier: "CollectionViewCell", for: indexPath)
            return item
        }

    return NSCollectionViewItem()
}

That's because item is not an object of CollectionViewCell. Option-click on item. – El Tomato Oct 29 '18 at 06:08
Tried this also let item = collectionView.makeItem(withIdentifier: "CollectionViewCell", for: indexPath) as! CollectionViewItem (i.e my custom class of nscollectionviewitem) – Aabid Khan Oct 29 '18 at 06:47
Instantiate CollectionViewCell with item. – El Tomato Oct 29 '18 at 07:22
Done that also still getting error , if any demo available on git ? – Aabid Khan Oct 29 '18 at 12:06
Is `nib` nil? What's inside the nib? – Willeke Oct 29 '18 at 13:42
No nib is not nil.Inside nib is a view loaded. – Aabid Khan Oct 30 '18 at 05:08
And a `NSCollectionViewItem`? – Willeke Nov 01 '18 at 22:57
