How to save related CoreData objects? #69

Closed riley-usagi closed 2 years ago

riley-usagi commented 2 years ago

Hi, @nalexn .

Could you please explain how to save (store) related objects (Parent -> Childs) to the database?

Thanks.

Hey @riley-usagi , you simply insert both parent and child objects in the managed context (calling insertNewObject on a concrete NSEntityDescription) and then assign the references between the objects. Here is an example in this repo, where a Country has 1-many relationship with NameTranslation (check out xcdatamodeld file)
