## Error Categories Fixed

### 1. Type System Mismatches
- **Issue:** `Int64` timestamps incompatible with Swift `Date(timeIntervalSince1970:)` which expects `Double`
- **Fix:** Explicit conversion: `Date(timeIntervalSince1970: Double(value) / 1000.0)`
- **Files:** `DailyNotificationTTLEnforcer.swift`, `DailyNotificationRollingWindow.swift`

### 2. Logger API Inconsistency
- **Issue:** Code called `logger.debug()`, `logger.error()` but API only provides `log(level:message:)`
- **Fix:** Updated to `logger.log(.debug, "\(TAG): message")` format
- **Files:** `DailyNotificationErrorHandler.swift`, `DailyNotificationPerformanceOptimizer.swift`, `DailyNotificationETagManager.swift`

### 3. Immutable Property Assignment
- **Issue:** Attempted to mutate `let` properties on `NotificationContent`
- **Fix:** Create new instances instead of mutating existing ones
- **Files:** `DailyNotificationBackgroundTaskManager.swift`

### 4. Missing Imports
- **Issue:** `CAPPluginCall` used without importing `Capacitor`
- **Fix:** Added `import Capacitor`
- **Files:** `DailyNotificationCallbacks.swift`

### 5. Access Control
- **Issue:** `private` properties inaccessible to extension methods
- **Fix:** Changed to `internal` (default) access level
- **Files:** `DailyNotificationPlugin.swift`

### 6. Phase 2 Features in Phase 1
- **Issue:** Code referenced CoreData `persistenceController` which doesn't exist in Phase 1
- **Fix:** Stubbed Phase 2 methods with TODO comments
- **Files:** `DailyNotificationBackgroundTasks.swift`, `DailyNotificationCallbacks.swift`

### 7. iOS API Availability
- **Issue:** `interruptionLevel` requires iOS 15.0+ but deployment target is iOS 13.0
- **Fix:** Added `#available(iOS 15.0, *)` checks
- **Files:** `DailyNotificationPlugin.swift`

### 8. Switch Exhaustiveness
- **Issue:** Missing `.scheduling` case in `ErrorCategory` switch
- **Fix:** Added missing case
- **Files:** `DailyNotificationErrorHandler.swift`

### 9. Variable Initialization
- **Issue:** Variables captured by closures before initialization
- **Fix:** Extract values from closures into local variables
- **Files:** `DailyNotificationErrorHandler.swift`

### 10. Capacitor API Signature
- **Issue:** `call.reject()` doesn't accept dictionary as error parameter
- **Fix:** Use `call.reject(message, code)` format
- **Files:** `DailyNotificationPlugin.swift`

### 11. Method Naming
- **Issue:** Called `execSQL()` but method is `executeSQL()`
- **Fix:** Updated to correct method name
- **Files:** `DailyNotificationPerformanceOptimizer.swift`

### 12. Async/Await
- **Issue:** Async function called in synchronous context
- **Fix:** Made functions `async throws` where needed
- **Files:** `DailyNotificationETagManager.swift`

### 13. Codable Conformance
- **Issue:** `NotificationContent` needed `Codable` for JSON encoding
- **Fix:** Added `Codable` protocol conformance
- **Files:** `NotificationContent.swift`

## Build Script Improvements

### Simulator Auto-Detection
- **Before:** Hardcoded "iPhone 15" (not available on all systems)
- **After:** Auto-detects available iPhone simulators using device ID (UUID)
- **Implementation:** Extracts device ID from `xcrun simctl list devices available`
- **Fallback:** Device name → Generic destination

### Workspace Path
- **Fix:** Corrected path to `test-apps/ios-test-app/ios/App/App.xcworkspace`

### CocoaPods Detection
- **Fix:** Handles both system and rbenv CocoaPods installations

## Statistics

- **Total Error Categories:** 13
- **Individual Errors Fixed:** ~50+
- **Files Modified:** 12 Swift files + 2 configuration files
- **Build Time:** Successful on first clean build after fixes

---

## Verification

**Build Command:**
```bash
./scripts/build-ios-test-app.sh --simulator
```

**Result:** ✅ BUILD SUCCEEDED

**Simulator Detection:** ✅ Working
- Detects: iPhone 17 Pro (ID: 68D19D08-4701-422C-AF61-2E21ACA1DD4C)
- Builds successfully for simulator

---

## Next Steps

1. ✅ Build successful
2. ⏳ Run test app on iOS Simulator
3. ⏳ Test Phase 1 plugin methods
4. ⏳ Verify notification scheduling
5. ⏳ Test background task execution

## Lessons Learned

See `doc/directives/0003-iOS-Android-Parity-Directive.md` Decision Log section for detailed lessons learned from each error category.

**Key Takeaways:**
- Always verify type compatibility when bridging platforms
- Check API contracts before using helper classes
- Swift's type system catches many errors at compile time
- Phase separation (Phase 1 vs Phase 2) requires careful code organization
- Auto-detection improves portability across environments
