How to run Swift Data and Core Data operations in the background and share models across concurrency contexts
Author: Pol.

Core Data is a powerful framework that allows you to manage the persistent model layer of your application and, while it is a first-party solution that has been a standard in the Apple ecosystem for many years, it is dated and is not straightforward to use.
In fact, the community has been asking for many years for a more modern and easier-to-use alternative to Core Data and, those wishes were finally granted with the introduction of the SwiftData framework in WWDC23. While SwiftData is much simpler to set up and interact with than Core Data, it is a wrapper around Core Data and, as such, it inherits a lot of the bagage that developers dreaded when working with Core Data.

This year at WWDC and iOS 18, we got some new features in Xcode and Swift that are making our lives as developers a bit better. We got a new Preview modifier and some new features for Core Data. I this series, I am going to show you some of those new features. In this, the first of two videos, I am going to show you how you can build a JSON file representing Mock Data and import it into a SwiftData models in an in Memory container that has both one to many and many to many relationship. Then we will build a preview modifier that will allow us to use that mock data in any one of our 4 views to display sample data.
