title: Whats the difference between moving between Storyboard scenes - Segues and Unwind
body: <p>I'm a fresher. I used segue to go (Flow of Execution) such like that</p>
  
  <pre><code> UIViewController A =&gt; UIViewController B =&gt; UIViewController C.
  </code></pre>
  
  <p>And used unwind segue to move from <strong>C to A</strong>. But I am confused about how they different of each other.
  And Why I use unwind segue  although I have delegation. </p>
  
  <p>Thank You in advance.</p>
