I follow this basic tutorial to start playing with JSQMessagesViewController:

How can I do to have a back button in the ChatViewController?
When debugging it seems to be here but maybe masked by something.
Thank you for any feedback. Regards
Your problem is that the "ChitChat" scene is the root ViewController; there's nothing to go back to!
Even though the Log-In screen appears before the ChiChat VC, you can see how it segues TO the Navigation Controller, which is Embedded in the ChitChat VC.
Think of it like this: Since the Log-In VC appears before the Navigation Controller, it never sees it, and doesn't know that there's a screen to go back to (this is simplified logic).
If you want to have a back button to go back to the Log-In VC, then try playing around with embedding the Navigation Controller in the Log-In VC (By using the editor tab, and then selecting "Embed in" in xCode, if you've never done this before)
