Liquid Glass

The current glass implementation is centered on a single reusable component: GlassToolbarContainer.

Files

• ios/SwiftLaunch/UI/Components/GlassToolbarContainer.swift — availability-gated glass toolbar container
• ios/SwiftLaunch/UI/Theme/BrandColors.swift — brand colors used across the UI

What is implemented

GlassToolbarContainer chooses a visual style at runtime:

enum VisualStyle: Equatable {
    case liquidGlass
    case materialFallback
}

Resolution logic:

• uses .liquidGlass on iOS 26+
• uses .materialFallback on iOS 17–25

On iOS 26+, it renders:

GlassEffectContainer {
    toolbarRow
        .glassEffect(.regular, in: toolbarShape)
}

Fallback rendering:

toolbarRow
    .background(.ultraThinMaterial, in: toolbarShape)

Usage

GlassToolbarContainer(
    title: "Dashboard",
    leading: AnyView(Image(systemName: "person.crop.circle.fill")),
    trailing: AnyView(Image(systemName: "gearshape.fill"))
) {
    Text("Content")
}

Current scope notes

• The shipped liquid-glass behavior is currently concentrated in GlassToolbarContainer.
• GlassToolbarContainer currently includes its own preview, but there are no production call sites yet.
