Layout

Layout Patterns (visionOS)

Window Default Sizing

Windows have no fixed frame — use .defaultSize():

WindowGroup {
    ContentView()
}
.defaultSize(width: 800, height: 600)

Volume Sizing

Volumes use 3D dimensions:

WindowGroup {
    VolumetricContentView()
}
.windowStyle(.volumetric)
.defaultSize(width: 0.5, height: 0.5, depth: 0.5, in: .meters)

Spatial Layout with Depth

Use depth alignment for layered content:

ZStack {
    BackgroundLayer()
    ContentLayer()
        .offset(z: 20)
    ForegroundLayer()
        .offset(z: 40)
}

Adaptive Sizing

GeometryReader { geometry in
    let columns = geometry.size.width > 800
        ? [GridItem(.adaptive(minimum: 200))]
        : [GridItem(.adaptive(minimum: 150))]

    LazyVGrid(columns: columns) {
        ForEach(items) { item in
            ItemCard(item: item)
        }
    }
}

Dynamic Type + Accessibility

@Environment(\.dynamicTypeSize) var dynamicTypeSize

var body: some View {
    VStack(spacing: AppTheme.Spacing.medium) {
        Text(title)
            .font(AppTheme.Fonts.headline)
        Text(subtitle)
            .font(AppTheme.Fonts.body)
    }
    .padding(AppTheme.Spacing.large)
}

Safe Area

visionOS windows have built-in safe areas:

VStack {
    content
}
.padding() // Respect default window padding

NOT Available on visionOS

• No device rotation — windows are freely positioned in space
• No split view controller — use multiple windows instead
• No UIScreen.main.bounds — windows are resizable
• No status bar or navigation bar background customization

Rules

1. Use .defaultSize() for initial window dimensions
2. Use .defaultSize(width:height:depth:in:) for volumetric windows
3. Use offset(z:) for depth-based layering
4. Use GeometryReader for adaptive layouts
5. Design for resizable windows — never assume fixed dimensions
6. Use AppTheme spacing tokens for consistent spatial layout
