title: How can you reload a ViewController after dismissing a modally presented view controller in Swift?
body: <p>I have a first tableViewController which opens up a second tableViewcontroller upon clicking a cell. The second view controller is presented modally (Show Detail segue) and is dismissed with:</p>
  
  <pre><code>self.dismissViewControllerAnimated(true, completion: {})
  </code></pre>
  
  <p>At this point, the second view controller slides away and reveals the first view controller underneath it. I would then like to reload the first view controller. I understand that this may require use of delegate functions, but not sure exactly how to implement it</p>
