Image cache using kingfisher

Question

I'm working on project in swift 3 and as to cache the image url that I get from json response I use the kingfisher pod. But for some reason I'm not getting the image in my UICollectionViewCell at all (image not getting displaying). What am I missing here. My code as below:

extension TableViewCell: UICollectionViewDelegate, UICollectionViewDataSource {


    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
          return arrayJson.count
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionViewCell", for: indexPath) as! CollectionViewCell

          cell.naeLabel.text = arrayJson[indexPath.row]?["title"].stringValue
        let url = ImageResource(downloadURL: URL(string: (arrayJson[indexPath.row]?["url"].stringValue)!)!, cacheKey: (arrayJson[indexPath.row]?["url"].stringValue))

        cell.ProfileimageView.kf.setImage(with: url)

        return cell    
    }
}
