SwiftData is a framework introduced in iOS 17 that simplifies building your app's model layer and persisting data across app launches. It integrates well with SwiftUI, allowing you to manage your app's data efficiently using modern Swift language features like macros.
In the context of MVVM (Model-View-ViewModel) architecture, SwiftData can be used to manage the model layer. You can define your data models using the model macro, which allows you to specify behaviors and relationships. SwiftData also supports custom data stores, enabling you to use different backends like SQLite or JSON files, which can be useful for persisting data in various formats.
For more details on SwiftData and its features, you can refer to the session What’s new in SwiftData (00:01:01) and Create a custom data store with SwiftData (00:13:00). These sessions cover the adoption of SwiftData, customization of schemas, and the creation of custom data stores, which are relevant to implementing the MVVM pattern in your app.
Create a custom data store with SwiftData
Combine the power of SwiftData’s expressive, declarative modeling API with your own persistence backend. Learn how to build a custom data store and explore how to progressively add persistence features in your app. To get the most out of this session, watch “Meet SwiftData” and “Model your schema with SwiftData” from WWDC23.
What’s new in SwiftData
SwiftData makes it easy to add persistence to your app with its expressive, declarative API. Learn about refinements to SwiftData, including compound uniqueness constraints, faster queries with #Index, queries in Xcode previews, and rich predicate expressions. Join us to explore how you can use all of these features to express richer models and improve performance in your app. To discover how to build a custom data store or use the history API in SwiftData, watch “Create a custom data store with SwiftData” and “Track model changes with SwiftData history”.
