How to set Image at current Cell (Kingfisher)? Swift

Question

I have an TableView with custom cells. Label smiles contain links.

How can I put Image from link to current ImageView'cell? My code

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let identifier = "ClientCell"
        self.cell = self.tableView.dequeueReusableCell(withIdentifier: identifier) as? customChatCell

let text = message[Constants.MessageFields.text] ?? ""
let selectedCell = self.tableView.cellForRow(at: indexPath) as? customChatCell

***

if text.range(of:"smiles") != nil {
            let url = URL(string: text)
            self.cell![indexPath.row].smile.kf.setImage(with: url)
        } 

***
}

not working. I'm getting error for line self.cell![indexPath.row].smile.kf.setImage(with: url)

Type 'customChatCell' has no subscript members

I'm using Kingfisher. If I use code

self.cell.smile.kf.setImage(with: url)

image putting into all cells, not for current.

Please help me fix it.

You should remove keeping the cell reference at class level. Your cellForRow should look like this,

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
       let identifier = "ClientCell"
       let cell = tableView.dequeueReusableCell(withIdentifier: identifier) as? customChatCell

       let text = message[Constants.MessageFields.text] ?? ""
       if text.range(of:"smiles") != nil {
            let url = URL(string: text)
            cell.smile.kf.setImage(with: url)
       } else {
           // Reset image to nil here if it has no url
           cell.smile.image = nil  
       }
} 

Remember, you are using a single UIView(i.e, customChatCell) for each cell in UITableView so when you dequeue a cell it's your responsibility to update/reset the UI elements according to your data for each cell.
