Thank you for the reply. I am currently busy with work but when I get off I will post a code and a screenshot of the main workspace layout. Yes, I meant the app terminates in crashes. Yes the setup is correct. I’m sorry if my question was hard to follow this is my first time posting an in a forum. I will definitely post code in a screenshot when I get the chance. => Is there an Encoder class ? There is no encoder class just the first view control Class in that file. => How is it that ViewController does not show as FirstViewController Scene I renamed the title If that ViewController.
