Analytics Setup

Analytics Setup Generator

Generate a protocol-based analytics infrastructure that makes it easy to swap providers without changing app code.

When This Skill Activates

Use this skill when the user:

• Asks to "add analytics" or "set up analytics"
• Mentions "TelemetryDeck", "Firebase Analytics", "Mixpanel"
• Wants to "track events" or "add telemetry"
• Asks about "privacy-friendly analytics"
• Wants to swap analytics providers

Key Feature: Swappable Providers

The generated code uses a protocol-based architecture:

// Your app uses the protocol
analytics.track(.buttonTapped("subscribe"))

// Swap providers by changing ONE line:
let analytics: AnalyticsService = TelemetryDeckAnalytics() // or FirebaseAnalytics()

Pre-Generation Checks

1. Project Context Detection

• [ ] Check for existing analytics implementations
• [ ] Look for TelemetryDeck/Firebase/Mixpanel in Package.swift or Podfile
• [ ] Identify source file locations

2. Conflict Detection

Search for existing analytics:

Glob: **/*Analytics*.swift, **/*Telemetry*.swift
Grep: "protocol.*Analytics" or "TelemetryDeck" or "Firebase"

If found, ask user:

• Extend existing analytics?
• Replace with new implementation?
• Add new provider to existing setup?

Configuration Questions

Ask user via AskUserQuestion:

1. Which provider(s)?

• TelemetryDeck (privacy-friendly, recommended)
• Firebase Analytics
• Mixpanel
• None (NoOp for now, add later)

1. What events to track?

• App lifecycle (launch, background, foreground)
• Screen views
• User actions (buttons, features used)
• Errors
• Custom events

1. User properties?

• App version
• Subscription status
• Custom properties

Generation Process

Step 1: Create Core Files

Always generate these files:

1. AnalyticsService.swift - Protocol (never changes)
2. AnalyticsEvent.swift - Event definitions (app-specific)
3. NoOpAnalytics.swift - For testing/privacy mode

Step 2: Create Selected Provider(s)

Based on user selection:

• TelemetryDeckAnalytics.swift
• FirebaseAnalytics.swift
• MixpanelAnalytics.swift

Step 3: Create Environment Integration

For SwiftUI apps:

• AnalyticsServiceKey.swift - Environment key for dependency injection

Step 4: Determine File Location

Check project structure:

• If Sources/ exists → Sources/Analytics/
• If App/ exists → App/Analytics/
• Otherwise → Analytics/

Output Format

After generation, provide:

Files Created

Sources/Analytics/
├── AnalyticsService.swift          # Protocol (stable interface)
├── AnalyticsEvent.swift            # Your app's events
├── Providers/
│   ├── NoOpAnalytics.swift         # Testing/privacy
│   └── [Provider]Analytics.swift   # Selected provider(s)
└── AnalyticsServiceKey.swift       # SwiftUI Environment (optional)

Integration Steps

App Entry Point:

@main
struct MyApp: App {
    // Choose your provider
    private let analytics: AnalyticsService = TelemetryDeckAnalytics(appID: "YOUR-APP-ID")

    init() {
        analytics.configure()
    }

    var body: some Scene {
        WindowGroup {
            ContentView()
                .environment(\.analytics, analytics)
        }
    }
}

Tracking Events:

struct ContentView: View {
    @Environment(\.analytics) private var analytics

    var body: some View {
        Button("Subscribe") {
            analytics.track(.buttonTapped("subscribe"))
        }
    }
}

Required Dependencies

TelemetryDeck:

// Package.swift
.package(url: "https://github.com/TelemetryDeck/SwiftClient", from: "1.0.0")

Firebase:

// Package.swift
.package(url: "https://github.com/firebase/firebase-ios-sdk", from: "10.0.0")
// Also requires GoogleService-Info.plist

Swapping Providers Later

To switch providers:

1. Add new provider file (or generate with this skill)
2. Change ONE line in App.swift:

// Before
private let analytics: AnalyticsService = TelemetryDeckAnalytics(...)

// After
private let analytics: AnalyticsService = FirebaseAnalytics()

Testing

• Use NoOpAnalytics() in tests and previews
• All tracking calls become no-ops
• No external dependencies in tests
