Add SwiftData to an Existing App

Read Original

This article provides a step-by-step tutorial for adding SwiftData to an existing app. It covers system requirements (Xcode 15, minimum deployment targets, SwiftUI dependency), essential SwiftData components like the @Model macro, .modelContainer() view modifier, @Query and @Environment property wrappers, and practical code examples for persisting data. Aimed at developers familiar with SwiftUI, it explains how to transition from Core Data or add SwiftData to apps with mixed Storyboard/SwiftUI views.
