Question

Objective-C

In what cases is it better to use SQLite, and in which Core Data?
At what level does a jun need to know Core Data and SQLite?

Answer 1

I would include in the initial level of knowledge of Core Data:
- Knowledge of the main elements of the Core Data stack
- Knowledge of the capabilities of the framework (for example, you can write not only to the database)
- The ability to write / read
- Working with the simplest links
In my opinion, for a junior, such knowledge is quite enough. I advise you to go through a few tutorials, try to write it yourself.
Then I advise you to read about NSFetchedResultsController, but at the beginning it is better to read examples without them.
And so there is a book "Pro Core Data for iOS", on Habré there is even a translation of the first 4 chapters: habrahabr.ru/post/198242
