Apply comprehensive enhancements to iOS prefetch plugin testing and validation system per directive requirements. Technical Correctness Improvements: - Enhanced BGTask scheduling with validation (60s minimum lead time) - Implemented one active task rule (cancel existing before scheduling) - Added graceful simulator error handling (Code=1 expected) - Follow Apple best practice: schedule next task immediately at execution - Ensure task completion even on expiration with guard flag - Improved error handling and structured logging Testing Coverage Expansion: - Added edge case scenarios table (7 scenarios: Background Refresh Off, Low Power Mode, Force-Quit, Timezone Change, DST, Multi-Day, Reboot) - Expanded failure injection tests (8 new negative-path scenarios) - Documented automated testing strategies (unit and integration tests) Validation Enhancements: - Added structured JSON logging schema for events - Provided log validation script (validate-ios-logs.sh) - Enhanced test run template with telemetry and state verification - Documented state integrity checks (content hash, schedule hash) - Added UI indicators and persistent test artifacts requirements Documentation Updates: - Enhanced IOS_PREFETCH_TESTING.md with comprehensive test strategies - Added Technical Correctness Requirements to IOS_TEST_APP_REQUIREMENTS.md - Expanded error handling test cases from 2 to 7 scenarios - Created ENHANCEMENTS_APPLIED.md summary document Files modified: - ios/Plugin/DailyNotificationBackgroundTaskTestHarness.swift: Enhanced with technical correctness improvements - doc/test-app-ios/IOS_PREFETCH_TESTING.md: Expanded testing coverage - doc/test-app-ios/IOS_TEST_APP_REQUIREMENTS.md: Added technical requirements - doc/test-app-ios/ENHANCEMENTS_APPLIED.md: New summary document
iOS Implementation
This directory contains the iOS-specific implementation of the DailyNotification plugin.
Current Implementation Status
✅ IMPLEMENTED:
- Basic plugin structure (
DailyNotificationPlugin.swift) - UserDefaults for local data storage
- Power management (
DailyNotificationPowerManager.swift) - Battery optimization handling
- iOS notification categories and actions
❌ NOT IMPLEMENTED (Planned):
BGTaskSchedulerfor background data fetching- Background task management
- Silent push nudge support
- T–lead prefetch logic
Implementation Details
The iOS implementation currently uses:
UNUserNotificationCenterfor notification management ✅UserDefaultsfor local data storage ✅- iOS notification categories and actions ✅
- Power management and battery optimization ✅
Planned additions:
BGTaskSchedulerfor background data fetching- Background task management
- Silent push support
Native Code Location
The native iOS implementation is located in the ios/ directory at the project root.
Key Components
DailyNotificationPlugin.swift: Main plugin class ✅DailyNotificationPowerManager.swift: Power state management ✅DailyNotificationConfig.swift: Configuration options ✅DailyNotificationMaintenanceWorker.swift: Maintenance tasks ✅DailyNotificationLogger.swift: Logging system ✅
Missing Components (Planned):
BackgroundTaskManager.swift: Handles background fetch schedulingNotificationManager.swift: Manages notification creation and displayDataStore.swift: Handles local data persistence
Implementation Notes
- Uses UserDefaults for lightweight data storage ✅
- Implements proper battery optimization handling ✅
- Supports iOS notification categories and actions ✅
- Handles background refresh limitations ✅
Planned Features:
- BGTaskScheduler for reliable background execution
- Silent push notification support
- Background task budget management
Testing
