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:

   • Adopting a custom store in Swift Data is straightforward with the new datastore protocol, which supports any persistence backend (Create a custom data store with SwiftData).

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).
