The JSONDecoder is mentioned in the context of creating a custom data store with SwiftData. In the session titled "Create a custom data store with SwiftData," it is explained that when implementing a data store that uses a JSON file to persist models, the JSONDecoder is used to load data from the file URL provided by the configuration. This is part of the process of handling a datastore fetch request, where the data in the store is loaded and a datastore fetch result is instantiated with the snapshots from the file. The JSONDecoder is utilized because the default snapshot is codable, allowing for easy loading of data.
For more details, you can refer to the session Create a custom data store with SwiftData (08:31).
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”.
Explore the Swift on Server ecosystem
Swift is a great language for writing your server applications, and powers critical services across Apple’s cloud products. We’ll explore tooling, delve into the Swift server package ecosystem, and demonstrate how to interact with databases and add observability to applications.
Create a custom data store with SwiftData
Combine the power of SwiftData’s expressive, declarative modeling API with your own persistence backend. Learn how to build a custom data store and explore how to progressively add persistence features in your app. To get the most out of this session, watch “Meet SwiftData” and “Model your schema with SwiftData” from WWDC23.
