💾 Swift Data for iOS

A minimal SwiftUI + SwiftData example for persisting a simple list on-device

📖 Overview

Swift Data for iOS is a concise, runnable learning example that shows how to use Apple's SwiftData framework together with SwiftUI. It demonstrates the core persistence loop: defining a @Model class, wiring up a ModelContainer, querying stored records with @Query, and inserting or deleting items through the modelContext. The app itself is a single screen where you type text, press return to save it, and swipe to delete — all persisted on-device across launches.

✨ What it covers

• Declaring a persistent model with the @Model macro (SwiftDataModel).
• Bootstrapping a ModelContainer at the app entry point and injecting it with .modelContainer(...).
• Reading persisted records reactively via the @Query property wrapper.
• Inserting new records into the store using @Environment(\.modelContext) and context.insert(...).
• Deleting records with context.delete(...) wired to SwiftUI's .onDelete swipe action.
• Using #Preview with an in-memory model container for fast SwiftUI previews.
