title: Present UIAlertController in UITableViewCell on Presented View Controller
body: <p>I want to show <code>UIAlertController</code> from <code>UITableViewCell</code> class. </p>
  
  <p>While searching I found that <code>UIApplication.shared.keyWindow?.rootViewController?.present</code> doing this will display it. </p>
  
  <p>Which works in the case if the opened <code>ViewController</code> is under <code>NavigationController</code> because my <code>rootViewController</code> is a <code>NavigationController</code> and the view under which the <code>cell</code> is being presented.</p>
  
  <p>So how can I present <code>UIAlertController</code> in <code>UITableViewCell</code> which is presented.</p>
