Platforms Supported: iOS

Swift Version: 5.0

Key Points​

  • Design a loosely coupled analytics service.
  • Use protocol-oriented programming to support multiple providers.
  • Implement dependency injection for flexible provider configuration.

Use Cases​

  • Logging analytics events in an iOS application.
  • Switching between different analytics providers without code changes.
  • Ensuring the analytics service is scalable and maintainable.

Alternative Approaches​

  • Directly integrating with a single provider (e.g., Firebase).
  • Using a third-party analytics library.
  • Creating a custom analytics backend.

Performance Considerations​

  • Ensure minimal performance overhead when logging events.
  • Handle asynchronous logging to avoid blocking the main thread.
  • Optimize for low memory footprint and efficient resource usage.

Code​

AnatylicsManager.swift
protocol AnalyticsProvider {
    func sendAnalyticsEvent(named name: String, metadata: [String : Any]?)
}

import FirebaseAnalytics

struct FirebaseAnalyticsProvider: AnalyticsProvider {
    func sendAnalyticsEvent(named name: String, metadata: [String : Any]?) {
        Analytics.logEvent(name, parameters: metadata)
    }
}

class AnalyticsManager {
    private var provider: AnalyticsProvider?
    static var shared = AnalyticsManager()
    private init() {}
    
    func configure(provider: AnalyticsProvider) {
        self.provider = provider
    }
    
    func track(eventName: String, metadata: [String: Any]?) {
        guard let provider = provider else {
            print("Analytics provider not provided.")
            return
        }
        provider.sendAnalyticsEvent(named: eventName, metadata: metadata)
    }
}
AppDelegate.swift
// Example configuration in AppDelegate
AnalyticsManager.shared.configure(provider: FirebaseAnalyticsProvider())

Usage Example​

// Tracking an event
AnalyticsManager.shared.track(eventName: "user_clicked_forgot_password", metadata: ["userID": "exampleUserID"])
