title: Unable to make outlet for UITableView
body: <p>I'm trying to put a tableview inside of a UIViewController but I'm unable to control drag from the UITableView into my view controller to make an outlet. When I try to drag, it refuses to make a prompt for an outlet. I've even tried to make an outlet myself and then drag from the view controller class to the table view but it refuses to link.</p>
  
  <p><a href="https://i.stack.imgur.com/0NgPA.png" rel="nofollow noreferrer">Here is my workspace</a></p>
  
  <p>Here are my classes for the Tableview:</p>
  
  <p>The Season Cell Class</p>
  
  <pre><code>import UIKit
  
  class SeasonCell: UITableViewCell {
       @IBOutlet weak var seasonLabel: UILabel!
  }
  </code></pre>
  
  <p>The Season Class</p>
  
  <pre><code>class Season: NSObject {
      var name: String
  
      init(name: String){
          self.name = name
      }
  
  }
  </code></pre>
  
  <p>The View Controller</p>
  
  <pre><code>class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
  
      var seasons = [Season]()
  
      //created myself, wont link
      @IBOutlet weak var seasonsTableView: UITableView!
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          seasons.append(Season(name: "2018 Cross Country Season"))
          seasonsTableView.delegate = self
          seasonsTableView.dataSource = self
      }
  
      func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
          return seasons.count
      }
  
      func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
          let cell = tableView.dequeueReusableCell(withIdentifier: "seasonCell", for: indexPath) as? SeasonCell
  
          // Configure the cell...
          let thisSeason = seasons[indexPath.row]
          cell?.seasonLabel?.text = thisSeason.name
  
          return cell!
      }
  
  
  }
  </code></pre>
