Data Persistence with SwiftData

An introduction to application data persistence using SwiftData, covering concepts and setting up a basic data model and persisting in an app.

Sorting and filtering the data fetched creates a more usable experience. Along with Searchable, these records can be narrowed down. Adding connection between data models with Relationships in SwiftData adds more functionality as well.

Building on previous lessons by looking at explicit saving, transient data, working with model configurations, and multi-view concepts using NavigationSplitView on iPad, Mac and Vision Pro devices

As the app scales, look at performance with large data sets, employing Swift concurrency, as well as synchronization with CloudKit. On macOS, employing a document model makes sense.

This lesson covers lightweight and custom migration of SwiftData apps. The second half covers converting an app from Core Data to SwiftData.
