Comprehensive iOS development guidance including Swift best practices, SwiftUI patterns, UI/UX review against HIG, and app planning. Use for iOS code review, best practices, accessibility audits, or planning new iOS apps.
Build, install, and launch an iOS app on a physical iPhone or iPad entirely from the command line (no Xcode GUI), using xcodebuild + devicectl. Use when the user wants to run, test, or screenshot their app on a real device without opening Xcode.
Build, install, launch, and screenshot an iOS app in the Simulator to verify a change visually. Use when the user wants to run the app, see a change live, screenshot the running app, or confirm a UI fix actually works (not just that it compiles).
Guides you through comprehensive iOS/Swift app planning and analysis. Use for new apps (concept to architecture) or existing apps (audit current state, plan improvements, evaluate tech stack). Covers product planning, technical decisions, UI/UX design, and distribution strategy.
Generates technical architecture specification from PRD. Covers architecture pattern, tech stack, data models, and app structure. Use when creating ARCHITECTURE.md or designing system architecture.
Generates detailed implementation guide with pseudo-code and step-by-step development instructions. Creates IMPLEMENTATION_GUIDE.md from PRD, Architecture, and UX specs. Use when creating development roadmap.

## Execution Instructions
When activated, follow these steps:
1. **Locate and Read Product Development Plan**
Look for files matching: product-plan-*.md If multiple exist, use the most recent If none exist, ask user to provide the file path
2. **Look for Market Research and Competitive Analysis** (Optional but Recommended)
Check for competitive analysis:
Check for market research:
If found, read and incorporate these insights. If not found, proceed with product plan data only.
3. **Extract Key Information**
From the product plan, extract:
- App idea/name
- Problem statement
- Target users and personas
- Core features (from MVP scope section)
- Positioning and value proposition
- Success criteria
- Timeline estimate
From competitive analysis (if available), extract:
- Key competitors and their weaknesses
- Feature gaps (opportunities)
- Differentiation strategy
- Pricing insights
From market research (if available), extract:
- TAM/SAM/SOM figures
- Market growth rate
- Entry barriers to address
- Revenue potential for success metrics
4. **Create Output Directory**
```bash
mkdir -p docs
Generate PRD Using the template above:
Write to File
Write the complete PRD to: docs/PRD.md
Present to User After generating the PRD, present a summary:
✅ Product Requirements Document generated!
📋 **PRD Summary**:
- Document: docs/PRD.md
- Features defined: [X] core features
- User stories: [Y] stories with acceptance criteria
- User flows: [Z] flows documented
- Open questions: [N] decisions needed
📊 **Data Sources Used**:
- Product Development Plan: ✅
- Competitive Analysis: [✅ Integrated / ⚠️ Not found - recommend running]
- Market Research: [✅ Integrated / ⚠️ Not found - recommend running]
**Next Steps**:
1. Review the PRD in docs/PRD.md
2. Answer open questions in Section 8
3. Provide feedback on any features
4. Once approved, we can proceed to architecture spec
Would you like me to make any changes to the PRD?
Iterate Based on Feedback If user requests changes:
When generating the PRD:
Be Specific: No generic statements like "the app should be user-friendly"
Be Actionable: Every feature should have clear acceptance criteria
Be Complete: Cover all aspects
Be Realistic: Based on MVP scope from product plan
Be Consistent: Terminology should match product plan
User: "Generate PRD from my product plan"
You:
This skill is typically:
The PRD serves as the source of truth for all downstream specifications.
