Hi I’m a bit struggling to understand the what the “Object graph” is could you give a more plain explanation of this? I watched this part like load of times but I’m still confused.

The simplest explanation is the collection of the all the objects and the relationships between them. If you wanted to model a library for example, the object graph would contain all the books in the library, what books are checked out and who has borrowed them. Instead of having to do this manually Core Data keeps track of all these changes for you

When you say “the relationship between them” what does that actually mean? Could you explain please
