🗄️ Core Data for Swift

A minimal SwiftUI + Core Data demo showing local CRUD persistence with MVVM

📖 Overview

Core Data for Swift is a compact iOS sample app that demonstrates how to persist data locally with Apple's Core Data framework in a SwiftUI app. It stores simple text items on device, lists them, and lets you delete them — all wired together with a clean MVVM structure. The project is a focused reference for the essential Core Data building blocks: a persistent container stack, a managed object model, @FetchRequest, and saving/deleting through a ViewModel.

✨ Features

• Persist text items to disk via an NSPersistentContainer-backed CoreDataStack singleton.
• Live-updating list of saved entities using SwiftUI's @FetchRequest with a sort descriptor and animation.
• Add on submit — type into a text field and press return to save a new ModelEntity (with a generated UUID).
• Swipe to delete items, with the delete persisted back to the managed object context.
• MVVM separation — the ViewModel owns save logic (including rollback() on failure), keeping the view declarative.
• Safe optionals — an Optional<String> extension unwraps Core Data's optional text attribute to a non-optional String.
