I study from video tutorials on YouTube, and there are lessons from 2-3 years ago, and since I downloaded xcode, I can’t figure out what’s what. I would be very grateful if you help me!
First time in xcode.
I recommend that you go through this tutorial, 100 Days of SwiftUI. He shows you exactly what to do in Xcode, which should help you get started.

You can also study Apple books "everyone can code".
