Simplifying Our Entities with SwiftData

Let’s start our journey to mastering iOS 18 with one of the most important and useful frameworks Apple has released in the last few years – SwiftData.

SwiftData is an excellent example of Swift macro usage, taking the old and beloved Core Data framework to a whole new level of simplicity and adapting it to the modern world of Swift and declarative programming.

In this chapter, we will do the following:

• Understand the SwiftData background
• Define a data model, including its relationships and attributes
• Learn about the SwiftData container and configurations
• Fetch and manipulate data using the model context
• Migrate our data to new version schemas

It’s going to be a long ride with an exciting new framework! So, after the technical requirements, let’s start with some background on the framework.
