16. **WhatsAppValidator** - WhatsApp validation
17. **YouTubeAudio-macOS** - YouTube audio extraction
18. **YouTubeTranscripts-macOS** - Video transcription tool
19. **And 3 additional apps**

---

## Key Architecture Patterns for Monitoring App

### 1. Entry Point Pattern (App Structure)

**MetaSchedulerApp.swift** (most sophisticated example):
```swift
@main
struct MetaSchedulerApp: App {
    let modelContainer: ModelContainer
    @StateObject private var dataManager = DataManager.shared

    // SwiftData initialization with schema
    // MenuBarExtra for quick access
    // Command menus for keyboard shortcuts
    // Task for async startup
}
```

**Pattern Elements:**
- Use `@main` for app entry point
- Initialize `SwiftData` ModelContainer with schema in `init()`
- Add environment object for data management
- Configure MenuBarExtra for status bar access
- Add command menus for keyboard shortcuts
- Use `.task { }` modifier for async startup services

### 2. Data Management - Service Layer Pattern

**Two Primary Approaches:**

**A. DataManager Singleton (All 17+ apps)**
```swift
@MainActor
class DataManager: ObservableObject {
    static let shared = DataManager()

    @Published var tasks: [ScheduledTask] = []
    @Published var isWatching = false

    private init() { }
}
```

**B. Actor-Based Services (MetaScheduler pattern)**
```swift
actor SystemMetricsService {
    static let shared = SystemMetricsService()

    func collectMetrics() async -> SystemMetricsRaw {
        // CPU, GPU, RAM, Battery, Network collection
        // Includes 5-second caching
    }
}

actor PowerMonitorService {
    static let shared = PowerMonitorService()
    // Power consumption tracking with TDP values
}

actor NotificationService {
    static let shared = NotificationService()
    // macOS notifications
}
```

### 3. System Metrics Collection

**From MetaScheduler (production-ready)**:

**SystemMetricsSnapshot @Model:**
- CPU usage percent
- GPU usage percent (Apple Silicon)
- RAM used/total/pressure
- Battery level, charging status
- Network latency & reachability
- LM Studio server status (2 servers monitored)
- n8n workflow status
- Computed properties for thresholds (low battery, high CPU)

**Platform-Specific Implementation:**
```swift
#if os(macOS)
import IOKit.ps
// Use mach_host_self(), host_statistics for CPU
// sysctl for chip detection
// IOKit for battery via SMCKit or direct APIs
#else
import UIKit
// iOS fallback implementations
#endif
```

### 4. Menu Bar Implementation

**MetaScheduler & ReputacaoDigital Pattern:**
```swift
MenuBarExtra("AppName", systemImage: "gauge.with.dots") {
    MenuBarView()
        .environmentObject(dataManager)
}
.menuBarExtraStyle(.window)
```

**Dynamic Icon:**
```swift
private var menuBarIcon: String {
    if dataManager.isWatching {
        return "gauge.with.dots.needle.67percent"
    } else {
        return "gauge.with.dots.needle.0percent"
    }
}
```

### 5. Persistent Data Storage

**Three Patterns Used:**

**A. SwiftData (MetaScheduler, 17Licoes)** - Modern approach
```swift
@Model
final class ScheduledTask {
    @Attribute(.unique) var id: String
    var timestamp: Date
    var status: TaskStatus
    var metrics: [SystemMetricsSnapshot]
}
```

**B. UserDefaults + JSON (ReputacaoDigital)**
```swift
@MainActor
class DataManager: ObservableObject {
    func save() {
        UserDefaults.standard.set(try? JSONEncoder().encode(data), forKey: "key")
    }
}
```

**C. 3-Layer Backup with FileManager (17Licoes)**
```swift
// Saves to: ~/Documents/app_data.json
// Creates automatic backups: _backup1, _backup2
// Debounced saves with 2-second delay
```

### 6. Background Monitoring Services

**ReputacaoDigital Pattern** (most monitoring-focused):
```swift
actor RSSService {
    // Monitors feeds for mentions
}

actor NotificationService {
    // Native macOS notifications (UNUserNotificationCenter)
    // Fallback: osascript for system notifications
}

actor ReportSchedulerService {
    // Periodic task scheduling
}
```

**Notification Setup:**
```swift
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .sound]) { granted, error in }

// Send notification
let request = UNNotificationRequest(
    identifier: UUID().uuidString,
    content: content,
    trigger: UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false)
)
center.add(request)
```

### 7. Keyboard Shortcuts & Commands

**Pattern from Multiple Apps:**
```swift
CommandMenu("Tasks") {
    Button("New Task") { }
        .keyboardShortcut("n", modifiers: [.command])

    Button("Refresh All") { }
        .keyboardShortcut("r", modifiers: [.command])

    Button("Execute Ready") { }
        .keyboardShortcut("e", modifiers: [.command, .shift])
}
```

### 8. Navigation Structure

**Three Common Patterns:**

**A. NavigationSplitView (NEOGWorkspaceManager, 17Licoes)**
- Best for macOS with sidebar
- Sidebar → List → Detail view

**B. TabView (iOS-compatible, MetaScheduler)**
- For iPhone compatibility

**C. Sidebar Navigation (All apps)**
```swift
NavigationSplitView {
    SidebarView()
        .frame(minWidth: 200)
} detail: {
    DetailView()
}
```

### 9. Configuration Files

**Package.swift Standard:**
```swift
// swift-tools-version: 5.9
import PackageDescription

let package = Package(
    name: "AppName",
    platforms: [.macOS(.v14)],
    products: [
        .executable(name: "AppName", targets: ["AppName"])
    ],
    targets: [
        .executableTarget(
            name: "AppName",
            path: "Sources"
        )
    ]
)
```

**Minimum Requirements:**
- Swift 5.9+
- macOS 14.0+ (Sonoma)
- Xcode 15+

### 10. Project Structure Patterns

**Standard Directory Layout:**
```
AppName/
├── Package.swift              # Build config
├── Sources/
│   ├── AppNameApp.swift       # @main entry point
│   ├── Models/                # @Model data classes
│   │   ├── MetricSnapshot.swift
│   │   └── Configuration.swift
│   ├── Services/              # actor services
│   │   ├── DataManager.swift  # @MainActor singleton
│   │   ├── MetricsService.swift
│   │   └── NotificationService.swift
│   ├── Views/
│   │   ├── ContentView.swift  # Main navigation
│   │   ├── Dashboard/         # Metric displays
│   │   ├── Settings/
│   │   ├── MenuBar/           # Menu bar popup
│   │   └── Components/        # Reusable widgets
│   └── Extensions/            # Color+Theme, etc.
└── Resources/                 # Images, sounds
```

### 11. Reusable Code Examples

**From Backend Services** (`~/Services/servers/`):
- `system-monitor-server.py` - System metrics (already production)
- `system-metrics-server.py` - WebSocket metrics server
- `wifi-api-server.py` - WiFi scanning (CoreWLAN)

**Key Pattern:** Apps often connect to these existing backends rather than reimplementing.

## Recommended Template for Monitoring App

**Best Practice Combination:**

1. **Use MetaScheduler as base template** - Has sophisticated monitoring patterns
2. **Adopt ReputacaoDigital's notification system** - Proven macOS notification handling
3. **Use SwiftData (not UserDefaults)** - Modern, performant, queryable
4. **Implement actor-based services** - Thread-safe concurrent operations
5. **Add MenuBarExtra** - For quick access status
6. **3-column NavigationSplitView** - Standard macOS app UX

**Service Layer Should Include:**
- `MetricsCollectionService` (actor) - Gathers system data
- `DataManager` (@MainActor) - Persistence & state management
- `NotificationService` (actor) - macOS notifications
- `BackgroundMonitoringService` (actor) - Periodic tasks

**View Hierarchy:**
- ContentView → NavigationSplitView
  - Sidebar → Category selection
  - List → Data display
  - Detail → Drill-down metrics
  - MenuBar → Quick status
