title: How to go through Views without reload them again if I return back Swift
body: <p>I have ViewController1 and ViewController2 . When i click a button on the ViewController1 should go to ViewController2 and when press a custom back button should return to ViewController1 without reloading its content for ex:- if i type something on ViewController1's text filed it should remain as it is.
  Does anyone knows any solution for this?</p>
