# iOS Phase 1 Implementation Checklist

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

---

## Implementation Verification

### ✅ Core Infrastructure

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

### ✅ Phase 1 Methods

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

### ✅ Background Tasks

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

### ✅ Thread Safety

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

### ✅ Error Handling

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

### ✅ Permission Management

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

### ✅ Integration Points

- [x] Plugin initialization (`load()`)
- [x] Background task setup (`setupBackgroundTasks()`)
- [x] Storage initialization
- [x] Scheduler initialization
- [x] State actor initialization
- [x] Health status method (`getHealthStatus()`)

### ✅ Utility Methods

- [x] `calculateNextScheduledTime()` - Time calculation
- [x] `calculateNextOccurrence()` - Scheduler utility
- [x] `getNextNotificationTime()` - Next time retrieval
- [x] `formatTime()` - Time formatting for logs

### ✅ Code Quality

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

---

## Testing Readiness

### Test Documentation

- [x] **IOS_PHASE1_TESTING_GUIDE.md** - Comprehensive testing guide created
- [x] **IOS_PHASE1_QUICK_REFERENCE.md** - Quick reference created
- [x] Testing checklist included
- [x] Debugging commands documented
- [x] 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
