Home Inventory Modular

A comprehensive home inventory management app built with SwiftUI and Domain-Driven Design (DDD) architecture, fully modernized with Swift 6 concurrency and featuring an advanced hybrid workflow system for seamless AI-human collaboration.

🚀 Swift 6 Migration Status

Current Status: 75% Complete - Critical Infrastructure Issues Require Attention

This project has undergone a comprehensive Swift 6 migration across 31 modules using coordinated automation. While significant progress has been achieved, critical infrastructure components require expert attention before full Swift 6 compliance.

Component	Status	Completion	Priority
Foundation Layer (4 modules)	✅ Excellent	95%	Low
Infrastructure Layer (4 modules)	❌ Critical Issues	45%	URGENT
Services Layer (6 modules)	⚠️ Dependent	70%	High
UI Layer (4 modules)	✅ Good	90%	Medium
Features Layer (10 modules)	✅ Good	85%	Medium
App Layer (3 modules)	✅ Good	80%	Low

Migration Achievements

• 31 modules successfully processed with automated tooling
• 32 git commits documenting systematic migration
• 500+ Swift files analyzed and updated
• ~121,397 lines of code modernized
• Build system maintained - project compiles successfully
• Architectural integrity preserved during migration

Critical Issues Requiring Attention

🚨 BLOCKING (Must Fix Immediately)

1. CoreDataStack Concurrency Violation - Core Data operations unsafe across concurrent contexts
2. APIClient Race Conditions - Network operations subject to shared state issues
3. SessionManager Singleton Anti-pattern - Authentication state management compromised

⚠️ High Priority

• Service layer dependency violations (architectural integrity)
• Memory management concerns in async contexts
• Actor isolation boundary crossings

Current Configuration

• Swift Version: 6.0 (upgraded)
• Strict Concurrency: Enabled with Swift 6 concurrency checking
• Status: Compiling successfully despite critical infrastructure concurrency violations
• Next Steps: Infrastructure layer remediation to achieve full compliance (estimated 2-4 weeks)

Migration Methodology

This Swift 6 migration employed an innovative approach using 31 dedicated automated instances, each responsible for a specific module. The migration followed a systematic layered approach:

1. Phase 1: Foundation & Infrastructure (dependency order)
2. Phase 2: Services layer (business logic)
3. Phase 3: UI layer (presentation components)
4. Phase 4: Features layer (user-facing functionality)
5. Phase 5: App layer (integration & lifecycle)

Each migration generated structured commits following the pattern:

feat: Complete [ModuleName] Swift 6 migration
- Updated for Swift 6 strict concurrency checking
- Added @Sendable conformance where needed
- Applied @MainActor to UI components and ViewModels
- Implemented proper actor-based patterns

This systematic approach ensured traceability and rollback capability for each module.

📋 Detailed Analysis: See SWIFT6_MIGRATION_AUDIT_REPORT.md for comprehensive findings and technical implementation guide.

🎯 Architecture: Domain-Driven Design

This app uses DDD principles for a clean, maintainable, and scalable architecture:

• Rich Domain Models: Business logic embedded in models, not services
• Zero Translation: Models flow unchanged from UI to persistence
• Type Safety: Invalid states impossible at compile time
• Repository Pattern: Clean separation between domain and infrastructure

See DDD_FRESH_START.md for details on using the DDD architecture.

🏗️ Architecture & Best Practices

Recent Architecture Improvements

The codebase has undergone significant architectural improvements:

1. Standardized Error Handling - All service errors now conform to ServiceError protocol
2. Circuit Breaker Pattern - External services protected against cascading failures
3. Configuration Management - AppConstants eliminates hardcoded values
4. Data-Driven Categories - JSON configuration for category definitions

See the Architecture Patterns Guide for detailed documentation.

ContentView.swift Development Guidelines

⚠️ IMPORTANT: ContentView.swift should ONLY be used as a high-level router. It must remain lightweight and free of business logic.

✅ DO:

• Use ContentView only for navigation state management
• Keep it under 100 lines of code
• Delegate all UI to specialized views
• Use environment objects for dependency injection
• Handle app lifecycle events (background/foreground)

❌ DON'T:

• Put UI components directly in ContentView
• Add business logic or networking code
• Create complex view hierarchies
• Use ContentView for anything other than routing

Example Structure:

struct ContentView: View {
    @StateObject private var appState = AppState()
    @Environment(\.scenePhase) var scenePhase
    
    var body: some View {
        Group {
            switch appState.navigationState {
            case .loading: LoadingView()
            case .main: MainTabView()
            case .onboarding: OnboardingView()
            case .error(let error): ErrorView(error: error)
            }
        }
        .environmentObject(appState)
    }
}

Key Architecture Components

1. ContentView.swift - App-level routing only
2. AppState.swift - Centralized state management
3. MainTabView.swift - Main navigation structure
4. HomeView.swift - Dashboard with integration status
5. LoadingView.swift - App initialization UI
6. OnboardingView.swift - First-time user experience
7. ErrorView.swift - Error state handling

Integration Features

The app includes three major integrations:

• Gmail Import - Automatic receipt scanning from email
• Voice Search - Voice-powered item search
• Family Sharing - Share inventory with family members

🚦 CI/CD Status

Automated Checks

Branch Protection

• main branch requires:
  • ✅ All CI checks passing
  • ✅ 1 approved review
  • ✅ Up-to-date with base branch
  • ✅ Squash merge only
  • ✅ Linear history enforced

Development Guidelines

View Composition

• Break views into components under ~100 lines
• Use private structs for sub-components
• Create separate files for complex views

State Management

• Use @StateObject for view-owned state
• Use @EnvironmentObject sparingly
• Prefer explicit dependency injection
• Keep business logic in ViewModels

Navigation

• Use enums for navigation states
• Centralize navigation logic
• Avoid hardcoded navigation paths

Best Practices

• Add meaningful previews for all views
• Include accessibility identifiers early
• Use @AppStorage only for UI preferences
• Handle errors gracefully with dedicated views

Swift 6 Concurrency Guidelines

• Use @MainActor for UI components and ViewModels
• Implement proper Sendable conformance for data types
• Avoid @unchecked Sendable unless absolutely necessary
• Use actors for shared mutable state instead of global singletons
• Monitor for actor isolation warnings during development
• Be cautious with weak self references in async contexts

🤖 Hybrid AI-Human Development Workflow

This project implements an advanced hybrid workflow system designed for seamless collaboration between AI assistants (like Claude) and human developers. The system ensures code quality while enabling rapid development.

Key Features

1. Two-Branch Strategy

   • main - Protected, review-gated, production-ready code
   • dev - Flexible development branch for rapid iteration

2. Automated Branch Management

   • Nightly rebase of dev onto main (3 AM UTC)
   • Automatic conflict detection and PR creation
   • Stale PR management (10 days warning, 30 days auto-close)

3. Intelligent Commit Controls

   • Maximum 30 files or 800 lines per commit
   • Enforced branch naming conventions (feat/, fix/, docs/, etc.)
   • Conventional commit message format validation
   • Protected file changes require PR review

4. AI-Friendly Development

   • Claude wrapper script for isolated branch development
   • Automatic push-on-commit for single source of truth
   • Smart pre-commit hooks with guidance messages
   • CODEOWNERS integration for self-review capability

Quick Start for AI Development

# Use the Claude wrapper for isolated development
./scripts/claude-branch.sh "implement new feature"

# The script will:
