title: Circular Image in UITableViewCell
body: <p>I'm trying to create circular Images inside of my TableViewCell but something is going wrong. I guess that the cornerRadius is to big because there is not any Image displayed with this Code. If I set the cornerRadius on 30 for example, I can see the Images rounded but not in a clear circle .Why is this not working ? </p>
  
  <pre><code>override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
  
      var cell = tableView.dequeueReusableCell(withIdentifier: "QuestionLine")
      cell = UITableViewCell(style: .subtitle, reuseIdentifier: "QuestionLine")
  
  
      let user = users[indexPath.row]
       cell?.textLabel?.text = user.question
       cell?.detailTextLabel?.text = user.name
  
       let image = UIImage(named: user.profilePicture)
       cell?.imageView?.image = image
       cell?.imageView?.layer.cornerRadius = (image?.size.width)! / 2
       cell?.imageView?.clipsToBounds = true
  
      return cell!
  
  }
  </code></pre>
