Date: 2025-11-13
Status: ✅ BUILD SUCCEEDED

---

Objective

Fix all Swift compilation errors to enable iOS test app building and testing.

---

Results

✅ BUILD SUCCEEDED
✅ All compilation errors resolved
✅ Test app ready for iOS Simulator testing

---

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:

./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
