## Overview

A small SwiftUI calculator: the app presents a button-and-display view, taps are handled by the view’s calculator logic, and the resulting state is shown in the display. The sampled source places the UI, button definitions, and arithmetic handling together in ContentView.swift; no separate arithmetic or persistence subsystem is evident.

Main entry points: [`Calculator/ContentView.swift`](https://github.com/afrazcodes/swiftui-calculator/blob/master/Calculator/ContentView.swift) (Calculator view), [`Calculator/CalculatorApp.swift`](https://github.com/afrazcodes/swiftui-calculator/blob/master/Calculator/CalculatorApp.swift) (Calculator app)
