title: How to set initial storyboard
body: <p>I have two storyboards one of them is default called <strong>Main</strong> and the other one I have just added is called <strong>Admin</strong>.</p>
  
  <p><strong>Main</strong> is used for customer, <strong>Admin</strong> is used for owner of the app.</p>
  
  <p>I wonder how do you set initial/main interface storyboard programmatically. </p>

  <p>P.S. I know how to change it via xcode but do not know programatically.</p>
