This function Code: func prepare(for segue: UIStoryboardSegue, sender: Any?) is something I'm trying to use in app. But I don't know what to use for UIStoryboardSegue. Something is required but I don't know what. I have only one storyboard Main.storyboard. I tried using that but it didn't work and I tried using the name of the segue that I want it to follow but that doesn't work either. How do I call this function?
