To use Swift Data to store blog posts, you can follow these steps based on the information from the WWDC sessions:
-
Model Your Data: Start by defining your blog post model. You can use Swift Data's model macro to define your schema. This involves creating a Swift class or struct and decorating it with the model macro to indicate that it should be persisted.
-
Configure the Model Container: Use the model container to manage your data models. You can customize the model container to specify where and how your data is stored. For example, you can use a custom data store if you want to store your data in a specific format like JSON or use a different backend.
-
Use Queries: Swift Data allows you to query your data efficiently. You can use the query macro to fetch blog posts from the model container. You can also optimize your queries using the index macro to make them faster, especially if you frequently sort or filter by certain properties.
-
Persist Data: Swift Data provides persistence across app launches. You can save changes to your data models, and Swift Data will handle the underlying storage, whether it's Core Data by default or a custom store you configure.
For more detailed guidance, you can refer to the session What’s new in SwiftData which covers adopting Swift Data, customizing the schema, and optimizing queries.

What’s new in SwiftData
SwiftData makes it easy to add persistence to your app with its expressive, declarative API. Learn about refinements to SwiftData, including compound uniqueness constraints, faster queries with #Index, queries in Xcode previews, and rich predicate expressions. Join us to explore how you can use all of these features to express richer models and improve performance in your app. To discover how to build a custom data store or use the history API in SwiftData, watch “Create a custom data store with SwiftData” and “Track model changes with SwiftData history”.
