In the "What's new in SwiftData" session at WWDC 2024, several new features and improvements were introduced for SwiftData, a framework designed to model and persist app data across Apple's platforms. Here are the key updates:
-
Schema Macro: A new schema macro helps avoid duplicate models, enhancing the efficiency of your data models.
-
Model Containers: There are new ways to set up and configure model containers, allowing for more flexibility in how data is managed within your app.
-
Query Optimization: You can now optimize queries with complex filters and use a new macro to improve performance, making data retrieval faster and more efficient.
-
Index Macro: The introduction of the index macro allows for more performant queries by indexing properties that are commonly queried together.
-
Unique Constraints: You can add unique constraints to your schema to prevent duplicate entries and improve data integrity.
-
History API: A new history API is available to track changes to your app's models, which is useful for features like syncing with a server or responding to changes from an app extension.
-
Custom Data Stores: SwiftData now supports custom data stores, allowing you to use alternative backends like SQLite or a remote web service, providing greater flexibility in data storage solutions.
