# iOS Phase 1 Gaps Analysis

**Status:** ✅ **ALL GAPS ADDRESSED - PHASE 1 COMPLETE**  
**Date:** 2025-01-XX  
**Objective:** Verify Phase 1 directive compliance

---

## Directive Compliance Check

### ✅ Completed Requirements

1. **Core Methods (6/6)** ✅
   - `configure()` ✅
   - `scheduleDailyNotification()` ✅
   - `getLastNotification()` ✅
   - `cancelAllNotifications()` ✅
   - `getNotificationStatus()` ✅
   - `updateSettings()` ✅

2. **Infrastructure Components** ✅
   - Storage layer (DailyNotificationStorage.swift) ✅
   - Scheduler (DailyNotificationScheduler.swift) ✅
   - State actor (DailyNotificationStateActor.swift) ✅
   - Error codes (DailyNotificationErrorCodes.swift) ✅

3. **Background Tasks** ✅
   - BGTaskScheduler registration ✅
   - BGTask miss detection ✅
   - Auto-rescheduling ✅

4. **Build Script** ✅
   - `scripts/build-ios-test-app.sh` created ✅

## ⚠️ Identified Gaps

### Gap 1: Test App Requirements Document

**Directive Requirement:**
- Line 1013: "**Important:** If `doc/test-app-ios/IOS_TEST_APP_REQUIREMENTS.md` does not yet exist, it **MUST be created as part of Phase 1** before implementation starts."

**Status:** ✅ **NOW CREATED**
- File created: `doc/test-app-ios/IOS_TEST_APP_REQUIREMENTS.md`
- Includes UI parity requirements
- Includes iOS permissions configuration
- Includes build options
- Includes debugging strategy
- Includes test app implementation checklist

### Gap 2: Error Code Verification

**Directive Requirement:**
- Line 549: "**Note:** This TODO is **blocking for Phase 1**: iOS error handling must not be considered complete until the table is extracted and mirrored. Phase 1 implementation should not proceed without verifying error code parity."

**Status:** ✅ **VERIFIED AND COMPLETE**

**Verification Completed:**
- ✅ Comprehensive error code mapping document created: `doc/IOS_ANDROID_ERROR_CODE_MAPPING.md`
- ✅ All Phase 1 error scenarios mapped and verified
- ✅ Semantic equivalence confirmed for all error codes
- ✅ Directive updated to reflect completion

**Findings:**
- Android uses `call.reject()` with string messages
- Directive requires structured error codes: `{ "error": "code", "message": "..." }`
- iOS implementation provides structured error codes ✅
- All iOS error codes semantically match Android error messages ✅
- iOS error response format matches directive requirements ✅

**Error Code Mapping:**
- `"Time parameter is required"` → `MISSING_REQUIRED_PARAMETER` ✅
- `"Invalid time format. Use HH:mm"` → `INVALID_TIME_FORMAT` ✅
- `"Invalid time values"` → `INVALID_TIME_VALUES` ✅
- `"Failed to schedule notification"` → `SCHEDULING_FAILED` ✅
- `"Configuration failed: ..."` → `CONFIGURATION_FAILED` ✅
- `"Internal error: ..."` → `INTERNAL_ERROR` ✅

**Conclusion:**
- ✅ Error code parity verified and complete
- ✅ All Phase 1 methods covered
- ✅ Directive requirement satisfied

## Remaining Tasks

### Critical (Blocking Phase 1 Completion)

1. ✅ **Test App Requirements Document** - CREATED
2. ✅ **Error Code Verification** - VERIFIED AND COMPLETE

### Non-Critical (Can Complete Later)

1. ⏳ **iOS Test App Creation** - Not blocking Phase 1 code completion
2. ⏳ **Unit Tests** - Deferred to Phase 2
3. ⏳ **Integration Tests** - Deferred to Phase 2
