Use when making design decisions, reviewing UI for HIG compliance, choosing colors/backgrounds/typography, or defending design choices - quick decision frameworks and checklists for Apple Human Interface Guidelines
Use when implementing Liquid Glass effects, reviewing UI for Liquid Glass adoption, debugging visual artifacts, optimizing performance, or requesting expert review of Liquid Glass implementation - provides comprehensive design principles, API patterns, and troubleshooting guidance from WWDC 2025....
Use when ANY Metal porting issue occurs - black screen, rendering artifacts, shader errors, wrong colors, performance regressions, GPU crashes
Use when converting shaders or looking up API equivalents - GLSL to MSL, HLSL to MSL, GL/DirectX to Metal mappings, MTKView setup code
Use when building ANY 2D or 3D game, game prototype, or interactive simulation with SpriteKit, SceneKit, or RealityKit. Covers scene graphs, ECS architecture, physics, actions, game loops, rendering, SwiftUI integration, SceneKit migration.
Use when physics contacts don't fire, objects tunnel through walls, frame rate drops, touches don't register, memory spikes, coordinate confusion, or scene transition crashes
Use when building 3D content, AR experiences, or spatial computing with RealityKit. Covers ECS architecture, SwiftUI integration, RealityView, AR anchors, materials, physics, interaction, multiplayer, performance.
Use when building SpriteKit games, implementing physics, actions, scene management, or debugging game performance. Covers scene graph, physics engine, actions system, game loop, rendering optimization.
Use when porting OpenGL/DirectX to Metal - translation layer vs native rewrite decisions, migration planning, anti-patterns
SpriteKit API reference — all node types, physics body creation, action catalog, texture atlases, constraints, scene setup, particles, SKRenderer
