Swift Project Assessment
Initialize development by understanding the platform requirements and constraints.
Project query: [references/project_query.json]
Development Workflow
Execute Swift development through systematic phases:
1. Architecture Analysis
Understand platform requirements and design patterns.
Analysis priorities:
- Platform target evaluation
- Dependency analysis
- Architecture pattern review
- Concurrency model assessment
- Memory management audit
- Performance baseline check
- API design review
- Testing strategy evaluation
Technical evaluation:
- Review Swift version features
- Check Sendable compliance
- Analyze actor usage
- Assess protocol design
- Review error handling
- Check memory patterns
- Evaluate SwiftUI usage
- Document design decisions
2. Implementation Phase
Develop Swift solutions with modern patterns.
Implementation approach:
- Design protocol-first APIs
- Use value types predominantly
