This commit introduces a comprehensive refactoring of the tag management
system, replacing the previous API-based approach with a Core Data-first
strategy for improved performance and offline support.
Major Changes:
Tag Management Architecture:
- Add CoreDataTagManagementView using @FetchRequest for reactive updates
- Implement cache-first sync strategy in LabelsRepository
- Create SyncTagsUseCase following Clean Architecture principles
- Add TagSortOrder enum for configurable tag sorting (by count/alphabetically)
- Mark LegacyTagManagementView as deprecated
Share Extension Improvements:
- Replace API-based tag loading with Core Data queries
- Display top 150 tags sorted by usage count
- Remove unnecessary label fetching logic
- Add "Most used tags" localized title
- Improve offline bookmark tag management
Main App Enhancements:
- Add tag sync triggers in AddBookmarkView and BookmarkLabelsView
- Implement user-configurable tag sorting in settings
- Add sort order indicator labels with localization
- Automatic UI updates via SwiftUI @FetchRequest reactivity
Settings & Configuration:
- Add TagSortOrder setting with persistence
- Refactor Settings model structure
- Add FontFamily and FontSize domain models
- Improve settings repository with tag sort order support
Use Case Layer:
- Add SyncTagsUseCase for background tag synchronization
- Update UseCaseFactory with tag sync support
- Add mock implementations for testing
Localization:
- Add German and English translations for:
- "Most used tags"
- "Sorted by usage count"
- "Sorted alphabetically"
Technical Improvements:
- Batch tag updates with conflict detection
- Background sync with silent failure handling
- Reduced server load through local caching
- Better separation of concerns following Clean Architecture
Major performance improvements to prevent crashes and lag when working with large label collections:
Main App:
- Switch to Core Data as primary source for labels (instant loading)
- Implement background API sync to keep labels up-to-date
- Add LazyVStack for efficient rendering of large label lists
- Use batch operations instead of individual queries (1 query vs 1000)
- Generate unique IDs for local labels to prevent duplicate warnings
Share Extension:
- Convert getTags() to async with background context
- Add saveTags() method with batch insert support
- Load labels from Core Data first, then sync with API
- Remove duplicate server reachability checks
- Reduce memory usage and prevent UI freezes
Technical Details:
- Labels now load instantly from local cache
- API sync happens in background without blocking UI
- Batch fetch operations for optimal database performance
- Proper error handling for offline scenarios
- Fixed duplicate ID warnings in ForEach loops
Fixes crashes and lag reported by users with 1000+ labels.
- Add thread-safe NSManagedObjectContext extension
- Fix EXC_BAD_ACCESS with performAndWait wrappers
- Add network error detection with retry functionality
- Change hero image to aspectFill for better layout
- Mark classes as @unchecked Sendable for Swift Concurrency
Add comprehensive offline bookmark support with sync capabilities:
- Implement offline bookmark storage using Core Data with App Group sharing
- Add Share Extension support for saving bookmarks when server unavailable
- Create LocalBookmarksSyncView for managing offline bookmark queue
- Add OfflineSyncManager for automatic and manual sync operations
- Implement ServerConnectivity monitoring and status handling
- Add badge notifications on More tab for pending offline bookmarks
- Fix tag pagination in Share Extension with unique IDs for proper rendering
- Update PhoneTabView with event-based badge count updates
- Add App Group entitlements for data sharing between main app and extension
The offline system provides seamless bookmark saving when disconnected,
with automatic sync when connection is restored and manual sync options.
