SwiftData and SwiftUI

SwiftData introduces a declarative Swift-native API. It allows developers to work with data persistence in iOS apps seamlessly, and like SwiftUI follows a purely declarative paradigm.

Let’s take a look at the features of SwiftData:

• SwiftData can perform automatic migrations of the underlying model data, allowing you to maintain a consistent state for the data after application updates. It simplifies the boilerplate and error-prone code associated with data migrations.
• SwiftData has live updates. One of its main features is the live updates to SwiftUI views when the underlying data changes, without the need for manual refreshes. This is consistent with SwiftUI design and is facilitated through the @Query property wrapper, which we will cover later in this chapter in the Fetching data section.
• SwiftData requires minimal code and has a straightforward setup. It leverages Swift’s modern structured concurrency features and does not...
