# HoroscopeApp Development Coding Conventions

## Project Organization

### 1. Module Structure
```

├── MainApp/           # Main Feature Module
├── HoroscopeApp/     # App Entry Point
├── HoroscopeAppTests/
└── HoroscopeAppUITests/
```

### 2. Feature Directory Structure
```
MainApp/Sources/MainApp/
├── Feature/
│   ├── Horoscope/
│   │   ├── View/
│   │   ├── Store/
│   │   └── Component/
│   └── Profile/
       ├── View/

## Critical Guidelines

### 1. Architecture Requirements
```
REQUIRED:
- TCA (The Composable Architecture)
- SwiftUI
- Modular Structure
```

### 2. Required Documentation
```
REQUIRED_FILES:
- Feature/*/README.md      # Feature documentation
- .swiftlint.yml          # SwiftLint rules
```

### 3. Dependency Rules
```
VERSIONING:
- ComposableArchitecture: 1.15.2+
- Alamofire: 5.10.1+
- Moya: 15.0.3+
```

## Code Style Guidelines

### 1. File Structure
```swift
import SwiftUI
import ComposableArchitecture

struct HoroscopeView: View {
    // MARK: - Property
    let store: StoreOf<Horoscope>
    
    // MARK: - Body
    var body: some View {
        content
    }
    
    // MARK: - Views
    @ViewBuilder
    private var content: some View {
        // Implementation
    }
}
```

### 2. Naming Conventions 
```
PATTERNS:

1. Features
{Feature}View.swift
- HoroscopeView.swift
- ProfileView.swift

2. Reducers
{Feature}.swift
- Horoscope.swift
- Profile.swift

3. Components
{Feature}{Component}.swift
- HoroscopeCard.swift
- ProfileHeader.swift
```

### 3. State Management
```swift
struct Horoscope: Reducer {
    struct State: Equatable {
        // State properties
    }
    
    enum Action {
        // Actions
    }
    
    var body: some ReducerOf<Self> {
        Reduce { state, action in
            // Implementation
        }
    }
}
```

### 4. View Modifiers
```swift
// PATTERN: Modifier ordering
View
    .frame(...)      // 1. Size
    .padding(...)    // 2. Padding
    .background(...) // 3. Background
    .onTapGesture   // 4. Interaction
```

## Testing Standards

### 1. Test Structure
```swift
final class HoroscopeTests: XCTestCase {
    // MARK: Property
    private var store: TestStore<Horoscope.State, Horoscope.Action>!
    
    // MARK: Setup
    override func setUp() {
        super.setUp()
        store = TestStore(
            initialState: .init(),
            reducer: Horoscope()
        )
    }
    
    // MARK: Test
    func test_whenActionReceived_thenStateUpdated() async {
        await store.send(.action) {
            $0.property = newValue
        }
    }
}
```

### 2. Test Coverage Requirements
```
COVERAGE:
- Reducers: 90%+ coverage
- Views: UI tests for critical paths
- Network: Mock responses required
```
```

이 규칙들은 현재 프로젝트의 구조와 사용 중인 라이브러리들(TCA, Alamofire, Moya)에 맞춰져 있습니다. 특히 TCA를 중심으로 한 아키텍처 패턴을 강조했습니다.
