- Replace multiple boolean properties with single OfflineBookmarkSyncState enum - Add Use Case pattern for OfflineSyncManager with dependency injection - Simplify LocalBookmarksSyncView using state-driven UI with external bindings - Convert OfflineBookmarksViewModel to use @Observable instead of ObservableObject - Move credentials from Core Data to Keychain for better persistence - Implement comprehensive database migration for App Group containers - Add structured logging throughout sync operations and API calls Architecture improvements follow MVVM principles with clean separation of concerns.
