iOS Phase 1 Implementation Checklist

Status: ✅ COMPLETE
Date: 2025-01-XX
Branch: ios-2

---

Implementation Verification

✅ Core Infrastructure

• DailyNotificationStorage.swift - Storage abstraction layer created
• DailyNotificationScheduler.swift - Scheduler implementation created
• DailyNotificationStateActor.swift - Thread-safe state access created
• DailyNotificationErrorCodes.swift - Error code constants created
• NotificationContent.swift - Updated to use Int64 (milliseconds)
• DailyNotificationDatabase.swift - Database stub methods added

✅ Phase 1 Methods

• configure() - Enhanced with full Android parity
• scheduleDailyNotification() - Main scheduling with prefetch
• getLastNotification() - Last notification retrieval
• cancelAllNotifications() - Cancel all notifications
• getNotificationStatus() - Status retrieval with next time
• updateSettings() - Settings update

✅ Background Tasks

• BGTaskScheduler registration
• Background fetch handler (handleBackgroundFetch)
• Background notify handler (handleBackgroundNotify)
• BGTask miss detection (checkForMissedBGTask)
• BGTask rescheduling (15-minute window)
• Successful run tracking

✅ Thread Safety

• State actor created and initialized
• All storage operations use state actor
• Background tasks use state actor
• Fallback for iOS < 13
• No direct concurrent access to shared state

✅ Error Handling

• Error code constants defined
• Structured error responses matching Android
• Error codes used in all Phase 1 methods
• Helper methods for error creation
• Error logging with codes

✅ Permission Management

• Permission auto-healing implemented
• Permission status checking
• Permission request handling
• Error codes for denied permissions
• Never silently succeed when denied

✅ Integration Points

• Plugin initialization (load())
• Background task setup (setupBackgroundTasks())
• Storage initialization
• Scheduler initialization
• State actor initialization
• Health status method (getHealthStatus())

✅ Utility Methods

• calculateNextScheduledTime() - Time calculation
• calculateNextOccurrence() - Scheduler utility
• getNextNotificationTime() - Next time retrieval
• formatTime() - Time formatting for logs

✅ Code Quality

• No linter errors
• All code compiles successfully
• File-level documentation
• Method-level documentation
• Type safety throughout
• Error handling comprehensive

---

Testing Readiness

Test Documentation

• IOS_PHASE1_TESTING_GUIDE.md - Comprehensive testing guide created
• IOS_PHASE1_QUICK_REFERENCE.md - Quick reference created
• Testing checklist included
• Debugging commands documented
• Common issues documented

Test App Status

• iOS test app created (test-apps/ios-test-app/)
• Build script created (scripts/build-ios-test-app.sh)
• Test app UI matches Android test app
• Permissions configured in Info.plist
• BGTask identifiers configured

---

Known Limitations (By Design)

Phase 1 Scope

• ✅ Single daily schedule only (one prefetch + one notification)
• ✅ Dummy content fetcher (static content, no network)
• ✅ No TTL enforcement (deferred to Phase 2)
• ✅ Simple reboot recovery (basic reschedule on launch)
• ✅ No rolling window (deferred to Phase 2)

Platform Constraints

• ✅ iOS timing tolerance: ±180 seconds (documented)
• ✅ iOS 64 notification limit (documented)
• ✅ BGTask execution window: ~30 seconds (handled)
• ✅ Background App Refresh required (documented)

---

Next Steps

Immediate

1. Create iOS Test App (test-apps/ios-test-app/)

   • Copy structure from android-test-app
   • Configure Info.plist with BGTask identifiers
   • Set up Capacitor plugin registration
   • Create HTML/JS UI matching Android test app

2. Create Build Script (scripts/build-ios-test-app.sh)

   • Check environment (xcodebuild, pod)
   • Install dependencies (pod install)
   • Build for simulator or device
   • Clear error messages

3. Manual Testing

   • Run test cases from IOS_PHASE1_TESTING_GUIDE.md
   • Verify all Phase 1 methods work
   • Test BGTask execution
   • Test notification delivery

Phase 2 Preparation

1. Review Phase 2 requirements
2. Plan rolling window implementation
3. Plan TTL enforcement integration
4. Plan reboot recovery enhancement
