I am using Xcode 11.6.
When I look at top level objects in the 4 squares on the top left, it shows me 2 files: UIViewController.h, and UISwipeGestureRecognizer.h
I ctrl-drag to the ViewController.swift file, which is opened in splitscreen. I don't know how to check whether it is in the right class, what does that mean?
I'm a beginner, so I don't really get what I am doing here. Thanks for trying to help though.
