SwiftData (iOS 17+)

Overview

SwiftData is Apple's modern persistence framework (iOS 17+), built on Core Data but Swift-native. You declare models with the @Model macro; a ModelContainer holds the store, a ModelContext performs inserts/updates/deletes, and @Query drives SwiftUI views reactively.

When to use

• Local persistence in a native iOS app (iOS 17+)
• SwiftUI-driven, reactive data display
• Migrating from Core Data to a Swift-native API
• NOT for code shared with Android → use sqldelight-patterns
