Perfeito! Agora vou fazer um resumo final e criar um relatório completo:


wc -l ~/Apps/macOS/17Licoes-macOS/Sources/**/*.swift 2>/dev/null | tail -1

Count Swift lines in all sources


find ~/Apps/macOS -maxdepth 1 -type d | wc -l

Count macOS app directories


grep -r "@Model" ~/Apps/macOS --include="*.swift" | wc -l

Count SwiftData models


grep -r "WKWebView\|WebKit" ~/Apps/macOS --include="*.swift" | cut -d: -f1 | sort -u

List apps using WebKit

## 3. PADRÕES DE UI/UX: SwiftUI vs AppKit

### SwiftUI (100% dos apps analisados)
- Todos os 34 apps usam **SwiftUI** como framework principal
- Compatível com iOS + macOS (multi-platform)
- Suporta condicional: `#if os(macOS)` para ajustes macOS

#### Exemplos:

```swift
// NavigationSplitView - Padrão macOS
NavigationSplitView(columnVisibility: $columnVisibility) {
    // Sidebar
    VStack(spacing: 0) {
        SidebarView(selectedLesson: $selectedLesson)
        Divider()
        // Bottom Navigation
    }
    .frame(minWidth: 280, idealWidth: 320)
} detail: {
    // Main content
    LessonDetailView(lesson: lesson)
}
```

#### Componentes Específicos macOS:
- `NavigationSplitView` (sidebar + detail)
- `Settings` scene para preferences window
- `Window` scene para additional windows
- `CommandGroup` para menus
- `@NSApplicationDelegateAdaptor` para app lifecycle
- `AppDelegate` para comportamento macOS

---

## 4. INTEGRAÇÃO COM SAFARI/WEBKIT

### Apps Usando WebKit (3 identificados):

1. **YouTubeTranscripts-macOS**
   - `WKWebView` para renderização de PDF/HTML
   - Usado em `TranscriptReadingViewModel.swift`
   - Para exportar transcripts como PDF visual

2. **PredictiveHistory-macOS**
   - `WKWebView` em `StudyView.swift`
   - Para exibição de conteúdo web
   - Layout responsivo (side-by-side com transcript)

3. **Outros Apps** (User-Agent spoofing para web scraping)
   - Usam `URLRequest` com User-Agent customizado
   - Não integram WebView nativa

### Padrão WebKit (WKWebView):

```swift
import WebKit

struct StudyView: View {
    var body: some View {
        Group {
            case .horizontal:
                HStack(spacing: 0) {
                    mainContent
                        .frame(minWidth: 400)

                    if showTranscript {
                        Divider()
                        transcriptPanel
                            .frame(width: min(400, geo.size.width * 0.35))
                    }
                }
        }
    }
}

// NSViewRepresentable para WKWebView
struct WebViewRepresentable: NSViewRepresentable {
    let config: WKWebViewConfiguration

    func makeNSView(context: Context) -> WKWebView {
        let webView = WKWebView(frame: .zero, configuration: config)
        return webView
    }

    func updateNSView(_ webView: WKWebView, context: Context) {
        // Update logic
    }
}
```

---

## 5. PADRÕES DE CÓDIGO SWIFT

### 5.1 Arquitetura MVVM

```
Model → ViewModel → View
```

Exemplo **17Licoes-macOS**:

```swift
// Models
struct Lesson: Identifiable, Codable, Equatable, Hashable {
    let id: UUID
    let number: Int
    let category: LessonCategory
    let title: String
    let content: [ContentBlock]
}

enum ContentBlock: Codable, Equatable, Hashable {
    case paragraph(String)
    case highlight(String)
    case quote(text: String, author: String)
    case list(items: [String], numbered: Bool)
    case framework(title: String, items: [FrameworkItem])
}

// Services (similar to ViewModel)
@MainActor
class DataManager: ObservableObject {
    static let shared = DataManager()

    @Published var lessons: [Lesson] = []
    @Published var userProgress: UserProgress = UserProgress()
    @Published var notes: [Note] = []
    @Published var gamification: GamificationProgress = GamificationProgress()

    // Debounced save
    private var saveCancellable: AnyCancellable?
    private let saveDebouncer = PassthroughSubject<Void, Never>()
}

// View
struct ContentView: View {
    @EnvironmentObject var dataManager: DataManager
    @EnvironmentObject var themeManager: ThemeManager

    var body: some View {
        NavigationSplitView(columnVisibility: $columnVisibility) {
            SidebarView(selectedLesson: $selectedLesson)
        } detail: {
            LessonDetailView(lesson: lesson)
        }
    }
}
```

### 5.2 Gerenciamento de Estado

```swift
// @StateObject para ownership
@StateObject private var dataManager = DataManager()

// @EnvironmentObject para sharing
@EnvironmentObject var dataManager: DataManager

// @AppStorage para UserDefaults
@AppStorage("tts_auto_scroll") var autoScrollEnabled = true

// @Published para reactivity
class ThemeManager: ObservableObject {
    @Published var currentTheme: ThemeMode {
        didSet {
            UserDefaults.standard.set(currentTheme.rawValue, forKey: "Theme")
        }
    }
}
```

### 5.3 Persistência de Dados

#### Opção 1: JSON + FileManager (17Licoes)
```swift
class DataManager: ObservableObject {
    private let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]

    private var progressPrimaryURL: URL {
        documentsURL.appendingPathComponent("17licoes_progress.json")
    }
    private var progressBackup1URL: URL {
        documentsURL.appendingPathComponent("17licoes_progress_backup1.json")
    }
    private var progressBackup2URL: URL {
        documentsURL.appendingPathComponent("17licoes_progress_backup2.json")
    }

    // 3-layer backup strategy
    func saveProgress() {
        // Rotate backups: primary -> backup1 -> backup2
    }
}
```

#### Opção 2: SwiftData (YouTubeTranscripts)
```swift
@Model
final class Course {
    var id: UUID
    var name: String
    var channelName: String

    @Relationship(deleteRule: .cascade, inverse: \CourseVideo.course)
    var videos: [CourseVideo]
}

@main
struct YouTubeTranscriptsApp: App {
    var sharedModelContainer: ModelContainer = {
        let schema = Schema([SavedVideo.self, Course.self, CourseVideo.self])
        let modelConfiguration = ModelConfiguration(
            schema: schema,
            url: appDataURL.appendingPathComponent("YouTubeTranscripts.store"),
            allowsSave: true
        )
        return try ModelContainer(for: schema, configurations: [modelConfiguration])
    }()
}
```

### 5.4 Enums com Associated Values e Encoding

```swift
enum LessonCategory: String, Codable, CaseIterable {
    case mentalidade = "Mentalidade"
    case diagnostico = "Diagnóstico"
    case mindset = "Mindset"

    var displayName: String { self.rawValue }
    var icon: String {
        switch self {
        case .mentalidade: return "brain.head.profile"
        case .diagnostico: return "stethoscope"
        case .mindset: return "lightbulb.fill"
        }
    }
    var color: Color {
        switch self {
        case .mentalidade: return Color(hex: "FF6B6B")
        case .diagnostico: return Color(hex: "4ECDC4")
        case .mindset: return Color(hex: "FFD93D")
        }
    }
}

// Custom Codable para ContentBlock
enum ContentBlock: Codable, Equatable, Hashable {
    case paragraph(String)
    case highlight(String)
    case quote(text: String, author: String)
    case list(items: [String], numbered: Bool)

    enum CodingKeys: String, CodingKey {
        case type, text, author, items, numbered
    }

    init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        let type = try container.decode(String.self, forKey: .type)

        switch type {
        case "paragraph":
            let text = try container.decode(String.self, forKey: .text)
            self = .paragraph(text)
        case "quote":
            let text = try container.decode(String.self, forKey: .text)
            let author = try container.decode(String.self, forKey: .author)
            self = .quote(text: text, author: author)
        // ...
        default:
            throw DecodingError.dataCorruptedError(...)
        }
    }

    func encode(to encoder: Encoder) throws {
        var container = encoder.container(keyedBy: CodingKeys.self)

        switch self {
        case .paragraph(let text):
            try container.encode("paragraph", forKey: .type)
            try container.encode(text, forKey: .text)
        case .quote(let text, let author):
            try container.encode("quote", forKey: .type)
            try container.encode(text, forKey: .text)
            try container.encode(author, forKey: .author)
        }
    }
}
```

### 5.5 Theme Management (Multi-plataforma)

```swift
@MainActor
class ThemeManager: ObservableObject {
    static let shared = ThemeManager()

    @Published var currentTheme: ThemeMode {
        didSet {
            UserDefaults.standard.set(currentTheme.rawValue, forKey: "Theme")
        }
    }

    private init() {
        if let saved = UserDefaults.standard.string(forKey: "Theme"),
           let theme = ThemeMode(rawValue: saved) {
            currentTheme = theme
        } else {
            currentTheme = .dark
        }
    }

    var isDark: Bool {
        switch currentTheme {
        case .dark: return true
        case .light: return false
        case .system:
            #if os(macOS)
            return NSApp.effectiveAppearance.bestMatch(from: [.darkAqua, .aqua]) == .darkAqua
            #else
            return UITraitCollection.current.userInterfaceStyle == .dark
            #endif
        }
    }

    func toggle() {
        currentTheme = currentTheme == .dark ? .light : .dark
    }
}

// Color Extensions
extension Color {
    init(hex: String) {
        let hex = hex.trimmingCharacters(in: CharacterSet.alphanumerics.inverted)
        var int: UInt64 = 0
        Scanner(string: hex).scanHexInt64(&int)
        let a, r, g, b: UInt64
        switch hex.count {
        case 3: // RGB (12-bit)
            (a, r, g, b) = (255, (int >> 8) * 17, (int >> 4 & 0xF) * 17, (int & 0xF) * 17)
        case 6: // RGB (24-bit)
            (a, r, g, b) = (255, int >> 16, int >> 8 & 0xFF, int & 0xFF)
        case 8: // ARGB (32-bit)
            (a, r, g, b) = (int >> 24, int >> 16 & 0xFF, int >> 8 & 0xFF, int & 0xFF)
        default:
            (a, r, g, b) = (255, 0, 0, 0)
        }
        self.init(
            .sRGB,
            red: Double(r) / 255,
            green: Double(g) / 255,
            blue: Double(b) / 255,
            opacity: Double(a) / 255
        )
    }

    // Dark Theme
    static let darkBgPrimary = Color(hex: "#0a0a0b")
    static let darkBgSecondary = Color(hex: "#111113")
    static let darkTextPrimary = Color(hex: "#f5f5f5")
    static let darkTextSecondary = Color(hex: "#a0a0a5")

    // Light Theme
    static let lightBgPrimary = Color(hex: "#faf9f7")
    static let lightBgSecondary = Color(hex: "#ffffff")
    static let lightTextPrimary = Color(hex: "#1a1a1a")
    static let lightTextSecondary = Color(hex: "#5a5a5a")

    // Accent
    static let accentGold = Color(hex: "#d4a853")
    static let accentCopper = Color(hex: "#c67b4e")
}

// Theme Colors Provider
struct ThemeColors {
    let isDark: Bool

    var bgPrimary: Color { isDark ? .darkBgPrimary : .lightBgPrimary }
    var textPrimary: Color { isDark ? .darkTextPrimary : .lightTextPrimary }
}
```

### 5.6 Custom Components Reutilizáveis

```swift
// Quote Component
struct QuoteView: View {
    let text: String
    let author: String

    var body: some View {
        VStack(alignment: .leading, spacing: 12) {
            HStack(alignment: .top, spacing: 12) {

    @EnvironmentObject var themeManager: ThemeManager

    var body: some View {
        Button(action: action) {
            VStack(spacing: 2) {
                ZStack(alignment: .topTrailing) {

                            .font(.system(size: 8, weight: .bold))
                            .foregroundColor(.white)
                            .padding(.horizontal, 4)

            }
        }
        .buttonStyle(.plain)

### 5.7 App Lifecycle e Commands

```swift
@main
struct YouTubeTranscriptsApp: App {
    @NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .commands {
            // File Menu
            CommandGroup(after: .newItem) {
                Button("New Transcript") {
                    sendCommandCompat(.newTranscript)
                }
                .keyboardShortcut("n", modifiers: [.command])

                Divider()

                Button("Export Transcript...") {
                    sendCommandCompat(.exportTranscript)
                }
                .keyboardShortcut("e", modifiers: [.command])
            }

            // View Menu
            CommandGroup(after: .toolbar) {
                Button("Increase Font Size") {
                    sendCommandCompat(.increaseFontSize)
                }
                .keyboardShortcut("+", modifiers: [.command])

                .keyboardShortcut(" ", modifiers: [])
            }
        }

        Settings {
            SettingsView()
        }

        Window("Diagnostics", id: "diagnostics") {
            DiagnosticsView()

// Notifications para comunicação entre views
extension Notification.Name {
    static let newTranscript = Notification.Name("newTranscript")
    static let exportTranscript = Notification.Name("exportTranscript")
    static let ttsPlayPause = Notification.Name("ttsPlayPause")
    static let findInTranscript = Notification.Name("findInTranscript")
}
```

### 5.8 Performance e Caching

```swift
@MainActor
final class TranscriptReadingViewModel: ObservableObject {
    // Performance Cache
    private var cachedMatchCount: Int?
    private var cachedSearchText: String = ""
    private var cachedWordCount: Int?
    private var cachedTranscriptHash: Int?

    // Lazy-loaded formatted transcript
    private lazy var _formattedTranscriptCache: String = {
        TextFormatter.shared.formatForReading(video.transcript)
    }()

    var wordCount: Int {
        let hash = video.transcript.hashValue
        if cachedTranscriptHash == hash, let cached = cachedWordCount {
            return cached
        }
        cachedTranscriptHash = hash
        cachedWordCount = video.transcript.split(separator: " ").count
        return cachedWordCount!
    }

    var matchCount: Int {
        guard !searchText.isEmpty else { return 0 }

        if searchText == cachedSearchText, let cached = cachedMatchCount {
            return cached
        }

        cachedSearchText = searchText
        let pattern = searchText.lowercased()
        let text = video.transcript.lowercased()
        var count = 0
        var searchRange = text.startIndex..<text.endIndex
        while let range = text.range(of: pattern, range: searchRange) {
            count += 1
            searchRange = range.upperBound..<text.endIndex
        }
        cachedMatchCount = count
        return count
    }
}
```
