MovieMapper iOS - Phase 3.1 & 7 Implementation Summary

Implementation Date

March 3, 2026

Phase 3.1: Main SwiftUI Views ✓

Created Views

1. BrowseView.swift (261 lines)

Purpose: Directory browsing and file management interface

Key Features:

• Directory picker using UIDocumentPickerViewController
• Non-recursive folder scanning (current directory only)
• Breadcrumb navigation with "Back" button
• File list display with:
  • Folder icons (📁 blue)
  • Media file details (duration, quality, FPS)
  • Tag badges (color-coded: purple=extra, orange=behind-the-scenes, red=delete)
  • Play button (enabled only when file is tagged)
• Floating action button: "Move Tagged"
• Drag-and-drop reordering (iOS 17+ .onMove)
• Swipe-to-delete (.onDelete)
• Progress indicator during directory scan
• Audit logging for all file operations

Integration Points:

• FileScanner.scanDirectory() - Non-recursive scanning with progress
• AuditLogger.log() - Log file moves to .audit files
• FileManager - File system operations
• Combine/async/await - State management

2. SearchView.swift (157 lines)

Purpose: TVDB show search and episode management

Key Features:

• Search bar with submit handling
• Show results with film icon thumbnails
• Season selection interface
• Episode count display
• Loading states during search
• Back navigation for show/season selection

Implementation Notes:

• TVDBClient integration uses placeholder simulation
• Actual TVDB API integration requires valid API key in environment
• Uses Show, Season, Episode data models
• NavigationLink for show/season selection navigation

3. FileListView.swift (249 lines)

Purpose: File listing with tagging and mapping features

Key Features:

• File list with drag-and-drop reordering (.onMove)
• Episode number editing capability
• Tag toggle button
• Floating action button: "Move Tagged"
• Show/season mapping with "Map All" button
• Delete files with swipe action
• Audit logging for operations

Integration Points:

• FileMapper.mapFiles() - Episode mapping to Jellyfin structure
• AuditLogger.log() - Operation logging
• FileManager - File system operations

Known Limitations

1. SearchView: TVDBClient integration is simulated; requires valid API key for actual TVDB API calls
2. BrowseView: UIDocumentPickerViewController integration may need additional testing on physical devices
3. FileListView: Episode number editing is basic; could be enhanced with validation
4. LSP Errors: IDE language server shows false-positive module resolution errors (doesn't affect compilation)

---

Next Steps

1. Test on physical iPad device
2. Implement actual TVDB API integration with valid API key
3. Add offline caching for TVDB data
4. Implement more robust error handling and user feedback
5. Add unit tests for all services
6. UI testing for navigation flows
7. Performance optimization for large directory scans
8. Add undo functionality for file operations

---
