title: Working with search bar on iOS 9
body: <p>I have a <code>cities</code> array that I want the user the add.</p>
  
  <p>On the <code>add screen</code> I want that when the user start typing, the options for the cities (from the array) will be displayed in a table view.</p>
  
  <p>I've searched on the internet for hours but everything seems to be old and not up-to-date (apple deprecated some things in iOS 8 and 9).</p>
  
  <p>I'm searching for an up-to-date tutorial on how to do it, anyone can help?</p>
  
  <p>Thank you!</p>
