what's new on swiftdata

In the "What's New in SwiftData" session at WWDC 2024, several new features and improvements were introduced for SwiftData. Here are the highlights:

1. Schema Macro: A new schema macro helps avoid duplicate models, making it easier to manage your data models efficiently.

2. Model Containers: There are new ways to set up and configure model containers, which enhance how data is managed and accessed within your app.

3. Query Optimization: The session covers how to optimize queries with complex filters and introduces a new macro to improve performance.

4. Custom Data Stores: SwiftData now supports custom data stores, allowing you to use alternative backends like SQLite, a remote web service, or JSON files. This flexibility is a significant enhancement for developers needing custom storage solutions.

5. History API: SwiftData history is a new feature that lets your app track modifications to its data, which is useful for syncing with servers or responding to changes from app extensions.

6. Index and Unique Constraints: The addition of index and unique constraints makes queries more efficient and ensures data integrity by preventing duplicate entries.
