SOC 직업 분류 기준
Choose and implement iOS architecture patterns (MVVM, TCA, Clean Architecture) based on feature complexity. Use when designing architecture for new features or refactoring existing code.
Implement VIP (View-Interactor-Presenter) Clean Architecture for iOS apps requiring maximum testability, unidirectional data flow, and protocol-based boundaries. Use when refactoring complex features or building enterprise apps with strict separation of concerns.
Use when architecting complex iOS apps with multiple features, long-term maintenance requirements, or team scalability needs. Use when refactoring Massive View Controllers or implementing testable architecture. Do NOT use for simple single-screen apps, rapid prototypes, or small utility tools.
Use when building UIKit interfaces without storyboards, setting up Auto Layout constraints with anchors, creating reusable UI components, or encountering layout constraint errors and ambiguous layout warnings
Use when implementing Realm database in iOS apps, encountering thread-safety errors, async/await crashes, performance issues with sync/writes, or integrating with Codable APIs
Use when implementing JSON encoding/decoding with Codable, handling API responses, encountering decoding errors, managing date formats, mapping snake_case to camelCase, or dealing with nested/inconsistent JSON structures

| description | Break down features into implementable tasks and choose architecture approach. Use when starting a new feature or receiving requirements that need technical decomposition. |
Systematic approach to decompose features into actionable tasks. For senior engineers who know how to code but need a structured thinking framework.
Use architecture-patterns skill to decide:
Phase 1: Foundation
Phase 2: Core Logic
Phase 3: UI
Phase 4: Integration
Phase 5: Quality
| Risk | Mitigation |
|---|---|
| Unknown APIs | Define contract early, use mocks |
| New technology | POC spike first, allocate learning time |
| Performance concerns | Profile early, plan caching/pagination |
| Tight deadline | Negotiate scope, identify MVP |
Rule of Thumb: Sum task estimates + 30-50% buffer
Break tasks into <1 day chunks. If a task feels >1 day, decompose further.
