title: Passing Data between View Controllers without segue
body: <p>I have hit a wall with my design. I am trying to pass the strings from one View Controller to another. Those 2 controllers are not connected with segue. I have attached the screenshoot of my Storyboard. I have a feeling that my only option is to use a Singleton, or would that be possible with delegates? without using the method: </p>
  
  <pre><code>override func prepare(for segue: UIStoryboardSegue, sender: Any?) 
  </code></pre>
  
  <p>I can not acces the VC1 by the segue identifier. How would that be possible without accessing the identifier?</p>
  
  <p>Please have a look at the image and let me know what options do I have and what would be the best to use here.</p>
