I have made a sample project to demonstrate the solution. It is working perfectly fine. See the gif!

You can download the sample project code using the link https://drive.google.com/file/d/1zF8Uq2H6eQYyrHU6KqnZu7b5cU_HtZY0/view?usp=sharing

Actually, you have to add a gesture recognizer to your image and attach an action to this gesture. See the implementation of cellforRowAt.

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

 let cell = tableView.dequeueReusableCell(withIdentifier:"TableViewCellUser") as! TableViewCellUser
 //handle image and its gesture

 cell.imgUser.image = userImagesArray[indexPath.row]
 //enable the interaction so that touch could be captured.
 cell.imgUser.isUserInteractionEnabled = true
 let gesture = UITapGestureRecognizer(target: self, action:  #selector(userImageTapped(gesture:)))
 gesture.numberOfTouchesRequired = 1
 gesture.delegate = self as? UIGestureRecognizerDelegate
 cell.imgUser.tag = indexPath.row
 cell.imgUser.addGestureRecognizer(gesture)
 //handle label
 cell.lblUserName.text = userNames[indexPath.row]
 return cell

}

//action on user tap

guard let indexPathRow = gesture.view?.tag else {
  return
}
print(indexPathRow)
guard indexPathRow >= 0 else {
  print("Array index must be greater than zero. Going to  return")
  return
}
selectedUserImage = userImagesArray[indexPathRow]
selectedUserName = userNames[indexPathRow]
self.performSegue(withIdentifier: "UsersToDetail", sender: self)

You can download the fully working code from the above mentiond link. Let me know in comments if any problem Occurs
