title: Custom UITableViewCell created using Storyboard shows no label data - Swift
body: <p>Problem: 
  I have a simple UITableViewController and want to display a label in a custom made cell. I created a simple UITableViewController with number of sections 1 and rows 4 hardcoded. in storyboard, customised the cell with a new label, gave it an identifier and mapped an outlet in the DemoTableViewCell as well. Below are snapshots of all the different snippets of the code. Still for me the label text assigned in the function is not getting displayed.</p>
  
  <pre><code>class DemoTableViewCell: UITableViewCell {
  
      @IBOutlet weak var demoLabel: UILabel!
  
  }
  </code></pre>
  
  <hr>
  
  <pre><code>override func numberOfSections(in tableView: UITableView) -&gt; Int {
      // #warning Incomplete implementation, return the number of sections
      return 1
  }
  
  override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -&gt; Int {
      // #warning Incomplete implementation, return the number of rows
      return 4
  }
  
  
  override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {
      let cell : DemoTableViewCell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath) as! DemoTableViewCell
  
      cell.demoLabel.text = "Override Label"
      // Configure the cell...
  
      return cell
  }
  </code></pre>
