SOLID Swift - Apple Best Practices 2026

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Analyze existing architecture
2. fuse-ai-pilot:research-expert - Verify Swift/Apple docs via Apple Docs MCP + Context7
3. XcodeBuildMCP - Build validation after code changes. Then run fuse-ai-pilot:sniper.

DRY - Reuse Before Creating (MANDATORY)

Before writing ANY new code:

1. Grep the codebase for similar protocols, services, or logic
2. Check shared locations: Core/Extensions/, Core/Utilities/, Core/Protocols/
3. If similar code exists -> extend/reuse instead of duplicate
4. If code will be used by 2+ features -> create it in Core/ directly
