title: Instantiate and Present a viewController in Swift
body: <h2>Issue</h2>
  <p>I started taking a look on the <code>Swift Programming Language</code>, and somehow I am not able to correctly type the initialization of a <code>UIViewController</code> from a specific <code>UIStoryboard</code>.</p>
  <p>In <code>Objective-C</code> I simply write:</p>
  <pre><code>UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@&quot;StoryboardName&quot; bundle:nil];
  UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@&quot;ViewControllerID&quot;];
  [self presentViewController:viewController animated:YES completion:nil];
  </code></pre>
  <p>Can anyone help me on how to achieve this on Swift?</p>
