Metal Migration
Porting OpenGL/OpenGL ES or DirectX code to Metal on Apple platforms.
When to Use This Skill
Use this skill when:
- Porting an OpenGL/OpenGL ES codebase to iOS/macOS
- Porting a DirectX codebase to Apple platforms
- Deciding between translation layer (MetalANGLE) vs native rewrite
- Planning a phased migration strategy
- Evaluating effort vs performance tradeoffs
Red Flags
❌ "Just use MetalANGLE and ship" — Translation layers add 10-30% overhead; fine for demos, not production
❌ "Convert shaders one-by-one without planning" — State management differs fundamentally; you'll rewrite twice
