Key Technologies Used

• Language: Swift 5.9+
• Framework: SwiftUI
• Concurrency: async/await, Actor isolation
• Video: AVKit (AVPlayer, AVPlayerViewController)
• Networking: URLSession with async/await
• Storage: Keychain (Security framework), UserDefaults
• Architecture: MVVM with centralized state management

---

Implementation Highlights

Modern Swift Features

1. Actor Isolation: All services are actors for thread safety
2. Async/Await: All asynchronous operations use modern concurrency
3. @MainActor: UI components isolated to main thread
4. Property Wrappers: @Published, @StateObject, @EnvironmentObject

SwiftUI Patterns

1. Environment Objects: AppState injected throughout view hierarchy
2. Navigation: NavigationStack with value-based navigation
3. Focus Engine: @FocusState for tvOS remote navigation
4. Async Image: AsyncImage for remote image loading

Security Practices

1. Keychain Storage: Sensitive credentials encrypted by system
2. No Password Storage: User password never persisted
3. Error Handling: Comprehensive error types with user-friendly messages
4. URL Validation: All URLs validated before use

tvOS Optimizations

1. Focus States: Visual feedback for focused items (scale, shadows)
2. Large Touch Targets: Buttons and cards sized for remote navigation
3. Card-Based UI: Grid layouts with large thumbnails
4. Native Controls: AVPlayerViewController for video playback

---

Code Quality

Principles Followed

• ✅ Single Responsibility Principle
• ✅ Dependency Injection via protocols and actors
• ✅ Error handling at every layer
• ✅ Thread safety via actor isolation
• ✅ Type safety with strong typing and Codable
• ✅ Separation of concerns (MVVM)

Testing Ready

All major components are testable:

• Services are actors with clear interfaces
• ViewModels are ObservableObjects with testable logic
• Models conform to Codable for serialization testing
• Parsers are pure functions

---

What is NOT Included

The following must be created separately:

1. Xcode Project File (.xcodeproj)

   • Create manually following NEXT_STEPS.md

2. App Icon

   • Required size: 1280x768 pixels for tvOS

3. Launch Screen

   • Can be added via Xcode storyboard

4. Tests

   • Unit tests and UI tests can be added

5. CI/CD Configuration

   • GitHub Actions, Fastlane, etc.

6. Web Service Implementation

   • Authentication endpoint must be created

---

Verification Commands

To verify all files are present:

# Count Swift files
find simvision -name "*.swift" | wc -l
# Expected: 24

# Count documentation files
ls *.md | wc -l
# Expected: 4 (README, ARCHITECTURE, NEXT_STEPS, FILES_CREATED)

# List all Swift files
find simvision -name "*.swift" | sort

# Check directory structure
tree simvision -L 3
