What’s new for swift data?

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

1. Schema Macro: A new schema macro was introduced to help 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 the flexibility and control over how data is managed within your app.

3. Query Optimization: The session covered how to optimize queries with complex filters and introduced a new macro to improve performance, making data retrieval more efficient.

4. Custom Data Stores: SwiftData now supports custom data stores, allowing developers to use alternative backends like SQLite, remote web services, or JSON files, providing greater flexibility in data storage solutions.

5. Indexing and Unique Constraints: New features like indexing and unique constraints were added to make queries more efficient and ensure data integrity by preventing duplicate entries.

6. History API: The session also introduced a history API that allows developers to track changes in the datastore, which is useful for synchronizing local changes with remote services.
