title: How does iOS connect a UI object to the view controller object
body: <p>I'm new to iOS development and not sure how iOS connects a UI object to the underlying view controller object.  In Android the UI element has an id set in the designer and used in the view but I don't see the same in Xcode only the following (in the ViewController.swift which doesn't seem to connect to a specific UI element):</p>
  
  <pre><code>@IBOutlet weak var statusLabel: UILabel!
  </code></pre>
  
  <p>where as in Android I'd do the following in OnCreate()</p>
  
  <pre><code>statusLabel = (TextView)findViewById(R.id.statusLabel);
  </code></pre>
