Any changes to swift data this year

This year, there have been several updates to Swift Data, as highlighted in the WWDC sessions:

1. Modeling Enhancements: Swift Data now includes a more flexible model subclassing, entity inheritance, and support for additional common data types like AttributedString. These enhancements make it easier to define and manage data models in Swift.

2. Schema and Indexing: New features such as the #Unique macro and #Index macro have been introduced. The #Index macro helps make queries more efficient by optimizing how properties are stored and retrieved, while the #Unique macro ensures that a set of properties has no duplicate entries.

3. Custom Data Stores: Swift Data now supports custom data stores, allowing developers to use alternative backends like SQLite, remote web services, or JSON files. This flexibility enables the use of Swift Data's API with a variety of storage solutions.

4. History API: The new history API allows developers to track changes in a datastore, which is useful for synchronizing local changes with remote services.

5. Performance Improvements: There are optimizations for query performance, including complex filters and a new macro to improve performance.
