## Overview

This SwiftUI iOS app lets users browse pizzas and create, inspect, edit, or delete them through a remote REST API. The app launches into a navigation-based list; list cards open the relevant workflows, whose views make their own network requests and decode or encode pizza data. Pizza records are represented by a Codable model. Image URLs are rendered with SwiftUI’s AsyncImage. The excerpts show these direct integrations; no separate persistence or networking layer is present.

Main entry points: [`pizza/PizzaListPage.swift`](https://github.com/sullaspqr/pizza.swift/blob/main/pizza/PizzaListPage.swift) (Pizza list), [`pizza/PizzaModPage.swift`](https://github.com/sullaspqr/pizza.swift/blob/main/pizza/PizzaModPage.swift) (Edit pizza), [`pizza/PizzaDelPage.swift`](https://github.com/sullaspqr/pizza.swift/blob/main/pizza/PizzaDelPage.swift) (Delete pizza), [`pizza/PizzaSinglePage.swift`](https://github.com/sullaspqr/pizza.swift/blob/main/pizza/PizzaSinglePage.swift) (Pizza details)
