You should consider using Swift Data for several reasons:
-
Ease of Use: Swift Data simplifies the process of building your app's model layer and persisting data across app launches. It provides a lightweight API that feels natural in Swift, allowing you to define your schema with minimal additions to a normal Swift class (Platforms State of the Union).
-
Powerful Features: The framework offers a range of features including persistence, modeling, schema migration, graph management, and synchronization with CloudKit (What’s new in SwiftData).
-
Custom Data Stores: Swift Data allows you to use custom data stores, enabling you to store data using alternative backends like SQLite, remote web services, or even collections of JSON files. This flexibility makes it possible to use Swift Data's API with various storage backends (Platforms State of the Union).
-
Efficient Queries: With features like the
indexmacro, you can make your queries more efficient by specifying which properties are commonly queried together. This helps in storing and retrieving data quickly (What’s new in SwiftData). -
Change Tracking: Swift Data provides access to the history of changes in a datastore, making it easy to inspect all recent changes. This is particularly useful for tracking local changes that need to be synced to a remote web service (Platforms State of the Union).
-
Integration with SwiftUI: Swift Data integrates seamlessly with SwiftUI, allowing you to connect and query models from your SwiftUI views. This makes it easier to build apps that are both powerful and efficient (SwiftUI essentials).

Track model changes with SwiftData history
Reveal the history of your model’s changes with SwiftData! Use the history API to understand when data store changes occurred, and learn how to use this information to build features like remote server sync and out-of-process change handing in your app. We’ll also cover how you can build support for the history API into a custom data store.
A Swift Tour: Explore Swift’s features and design
Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.
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”.
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.
