title: DTTableViewmanager: Cell mapping is missing for model
body: <p>I am using a <a href="https://cocoapods.org/pods/DTTableViewManager" rel="nofollow noreferrer">DTTableViewManager</a> for my <code>UIViewController</code> with a <code>UITableView</code> contained within. </p>
  
  <p>My View Controller only contains: </p>
  
  <pre><code>class ViewController: UIViewController, DTTableViewManageable {
  
      @IBOutlet weak var tableView: UITableView!
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          let users = ["Test User 1", "Test User 2"]
  
          manager.startManaging(withDelegate: self)
          manager.register(PersonsCell.self)
          manager.memoryStorage.addItem(users, toSection: 0)
  
      }
  
  }
  </code></pre>
  
  <p>This is conform their Github <a href="https://github.com/DenHeadless/DTTableViewManager/blob/master/Example/Example%20controllers/CustomViewsController.swift" rel="nofollow noreferrer">example</a></p>
  
  <p>My <code>UITableViewCell</code> looks as follows: </p>
  
  <pre><code>class PersonsCell: UITableViewCell, ModelTransfer {
  
      func update(with model: String) {
          self.nameLabel = model        
      }
  
      @IBOutlet weak var nameLabel: UILabel!
  }
  </code></pre>
  
  <p>This is also conform their <a href="https://github.com/DenHeadless/DTTableViewManager/blob/master/Example/Cells/CustomStringCell.swift" rel="nofollow noreferrer">example</a> on Github.</p>
  
  <p>But still I'm getting this error: </p>
  
  <blockquote>
    <p>fatal error: Cell mapping is missing for model: ["Test User 1", "Test User 2"]: file ~~ ~/Pods/DTTableViewManager/Source/DTTableViewManager.swift, line 737</p>

  <p>I have tried to find examples for people with similar problems but I could not find them. </p>
