CoreData vs JSON files on disk

Forums > SwiftUI

I'm working on persisting data for my app on disk. My first implementation is to just save JSON files on disk. This works well, I can open the files up and see that the data is saved as expected. But I wonder if CoreData would be better for this task? What advantages does CoreData provide over JSON files?

CoreData has built-in options for performing database operations, such as sorting, filtering, relationships, cascade deletes, multi-threading, and many other things. CoreData has some difficult concepts and I have found it difficult to find good explanations on implementing some of this stuff; basically there's a much steeper learning curve.

Working with json files is much easier if you don't require any of the more advanced features.
