📱 iOS/iPadOS Application - Architecture and Implementation Plan

This pull request provides comprehensive documentation and planning for developing the Deep Assistant iOS/iPadOS application (Issue #5).

📋 Issue Reference

Fixes #5 - Standalone iOS/iPadOS application at AppStore

---

📚 Documentation Added

1. iOS Application Architecture (IOS_APP_ARCHITECTURE.md)

A complete architectural design document covering:

System Architecture

• Architecture Pattern: MVVM (Model-View-ViewModel) + Clean Architecture
• UI Framework: SwiftUI (native iOS)
• Target Platform: iOS 16.0+ / iPadOS 16.0+
• Language: Swift 5.9+

Layer Structure

• Presentation Layer: SwiftUI Views + ViewModels
• Domain Layer: Use Cases + Entities + Repository Protocols
• Data Layer: Repository Implementations + Local/Remote Data Sources
• Network Layer: API Client + Authentication + WebSocket

Key Features Planned

• ✅ Chat interface with multiple AI models
• ✅ Model selection (GPT-4o, Claude, DeepSeek, Llama, etc.)
• ✅ Token balance management
• ✅ Conversation history with sync
• ✅ System message customization
• ✅ Dark mode support
• ✅ Localization (English, Russian)
• ✅ Offline support with local caching
• ✅ iCloud sync (future)

API Integration

The app will integrate with the existing API Gateway using the same endpoints as the Telegram bot:

• POST /completions - Send chat messages
• GET/PUT /token - Manage token balance
• GET/DELETE /dialog - Conversation management
• POST /referral - Referral system

Technical Highlights

• Security: Keychain for token storage, SSL pinning, data encryption
• Performance: Lazy loading, pagination, caching, background refresh
• Accessibility: VoiceOver, Dynamic Type, high contrast, reduced motion
• Testing: Unit tests, Integration tests, UI tests (target 80%+ coverage)

1. Application Type: Native Swift/SwiftUI or cross-platform (React Native, Flutter)?
2. Core Features: What features should be in the initial MVP vs later versions?
3. Backend Integration: Use existing API Gateway or need modifications?
4. Authentication: Per-user tokens or admin token approach?
5. User Experience: Offline mode? Push notifications? iCloud sync?
6. Technical Requirements: Minimum iOS version? iPhone and iPad support?
7. Branding: App name, design guidelines, color scheme?
8. Development Priorities: What's the MVP scope?

• Separation of Concerns: Clear layer boundaries
• Scalability: Easy to add features
• Maintainability: Code is organized and predictable
• Team Collaboration: Clear structure helps multiple developers

Why Core Data?

• Native: Built into iOS
• Performance: Optimized for iOS
• iCloud Sync: Future-ready
• Proven: Battle-tested by millions of apps
