title: want to create a search bar like google in swift
body: <p>I have an array like ["apple","appear","Azhar","code","BCom"] etc. This array contain more than half a million of records.</p>
  
  <p>Now what I want to do, is to place a <code>UISearchBar</code> like in google and then whenever user types a text, then the dropdown list would appear with all the results containing this text and user could select one from the list.</p>
  
  <p>For example - if the user types "a", then "apple","appear" and "Azhar" would appear in a drop-down list.</p>
  
  <p>I don't want to use a <code>UITableView</code> or anything else to load the records. Whenever user types any word it should collect records from the array and make a drop down to display them.</p>
  
  <p>How can I do this? 
  Suggestions required please.</p>
