What's New in Swift Data

Swift Data has introduced several new features and improvements to enhance data modeling, persistence, and querying capabilities. Here are the key updates:

  1. Custom Data Stores:

    • Swift Data now supports custom data stores, allowing you to use alternative backends like SQLite, remote web services, or even collections of JSON files. This flexibility enables the use of Swift Data's API with various storage solutions (Platforms State of the Union).

  2. Schema Macro:

    • A new schema macro helps avoid duplicate models, making it easier to set up and configure model containers (What’s new in SwiftData).

  3. Index and Unique Macros:

    • The index macro improves query efficiency by indicating which properties are commonly queried together.
    • The unique macro ensures that a set of properties has no duplicate entries (Platforms State of the Union).

  4. History API:

    • Swift Data now provides access to the history of changes in a datastore, making it easier to track local changes that need to be synced to a remote web service (What’s new in SwiftData).

  5. Previewable Macro:

    • The new previewable macro works well with Swift Data, facilitating easier query work while iterating on views (Platforms State of the Union).

  6. Custom Store Implementation:

  7. Modeling and Migration:

    • Swift Data continues to provide robust support for modeling, migration, graph management, and synchronization with CloudKit (What’s new in SwiftData).

Track model changes with SwiftData history

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.

Create a custom data store with SwiftData

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.

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”.

A Swift Tour: Explore Swift’s features and design

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.

Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
