What the code above shows on iPhone, after three taps.

Overview

You declare what the screen should look like for a given state. When the state changes, SwiftUI works out what to redraw. Layout, accessibility, Dark Mode and localization come along by default.

View

A lightweight description of a piece of UI. Compose small views into bigger ones.

@State

Local, view-owned values. Change one and the views that read it update.

@Observable

Share model objects across views; only what reads a property re-renders.

NavigationStack

Data-driven navigation with a path you can push, pop and restore.

ContentView.swift

struct ContentView: View {
    @State private var count = 0

    var body: some View {
        VStack(spacing: 16) {
            Text("Tapped \(count) times")
                .font(.title)
            Button("Tap") { count += 1 }
                .buttonStyle(.borderedProminent)
        }
    }
}
