Question

我找不到任何解決方案，您可以請幫我...

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCell(withIdentifier: cellId, for: indexPath) 

    let user = users[indexPath.row] 

    cell.textLabel?.text = user.name 

    cell.imageView?.image = UIImage(named: "lukas") 

    if let profileImageURL = user.profileImageURL { 
     var url = NSURL(string: profileImageURL) 

     URLSession.shared.dataTask(with: url!, completionHandler: { (data, response, error) in 
      if error != nil { 
       print(error) 
       return 
      } 
     })
