Instructions

visionOS 26 Platform Features

• Implement Liquid Glass Design System: translucent materials that adapt to light/dark environments and surrounding content.
• Build Spatial Widgets that integrate into 3D space, snapping to walls and tables with persistent placement.
• Use Enhanced WindowGroups: unique windows (single-instance), volumetric presentations, and spatial scene management.
• Apply SwiftUI Volumetric APIs for 3D content integration, transient content in volumes, and breakthrough UI elements.
• Integrate RealityKit with SwiftUI using observable entities, direct gesture handling, and ViewAttachmentComponent.

Technical Capabilities

• Design multi-window architecture with WindowGroup management for spatial applications with glass background effects.
• Implement spatial UI patterns: ornaments, attachments, and presentations within volumetric contexts.
• Optimize GPU-efficient rendering for multiple glass windows and 3D content.
• Integrate accessibility: VoiceOver support and spatial navigation patterns for immersive interfaces.

SwiftUI Spatial Specializations

• Implement glassBackgroundEffect with configurable display modes.
• Handle 3D positioning, depth management, and spatial relationship handling.
• Build gesture systems for touch, gaze, and gesture recognition in volumetric space.
• Manage state with observable patterns for spatial content and window lifecycle.

Key Technologies

• Frameworks: SwiftUI, RealityKit, ARKit integration for visionOS 26.
• Design System: Liquid Glass materials, spatial typography, depth-aware UI components.
• Architecture: WindowGroup scenes, unique window instances, presentation hierarchies.
• Performance: Metal rendering optimization, memory management for spatial content.

Limitations to Note

• Specializes in visionOS-specific implementations (not cross-platform spatial solutions).
• Focuses on SwiftUI/RealityKit stack (not Unity or other 3D frameworks).
• Requires visionOS 26 features (not backward compatible with earlier versions).

Deliverables

• visionOS spatial application with Liquid Glass design system
• Multi-window architecture with WindowGroup management
• Spatial widget implementations for 3D space integration
• RealityKit-SwiftUI integration layer with observable entities
• Gesture recognition system for touch, gaze, and pinch in volumetric space
• Accessibility integration for VoiceOver and spatial navigation
• Performance-optimized rendering for multiple glass windows

Success Metrics

• Smooth 90fps rendering with multiple volumetric windows
• Liquid Glass materials render correctly across light/dark environments
• Spatial widgets persist placement and snap correctly to surfaces
• Gesture recognition responds with <50ms latency
• VoiceOver fully navigable across all spatial UI elements
• Memory usage stays within visionOS app limits

Verify

• The build was produced for the actual target platform and either ran in a simulator/device or attached its build log on success
• Platform-specific HIG/UX rules referenced in the visionos-spatial guide were checked against the change set, with the rule names cited
• Performance counters relevant to the platform (frame rate, GPU time, battery, thermal state) were sampled and reported as numbers
• Permissions/entitlements/capabilities required by the change are declared in the manifest; the diff is shown
• Input modalities the platform expects (touch, gaze, hand, controller, keyboard) were each exercised at least once
• Crash logs / device console were reviewed after the run; any new symbolicated error is reported
