Help to understand SwiftData

Hello!

I apologize in advance if I chose the wrong topic for my question, this is my first time on this forum.

I am a novice developer and I am creating an application. I use Swift + SwiftUI, but I ran into such a problem that I have nowhere to store my data and I do not know how to store it correctly. I know that there is a SwiftData framework that is used to work with data, but I don't understand the documentation.

Please be understanding. How do I start learning SwiftData? What topics should be studied? What is the order of studying topics? Thank you all in advance!
