Google Reporter

Easily integrate Google Analytics into your iOS, macOS, and tvOS app without downloading any of the Google SDKs.

Swift 4/Xcode 9 Support: Please use the swift-4 branch.

Set Up

Works with Carthage or just put GoogleReporter.swift into your project.

From your AppDelegate's didFinishLaunchingWithOptions or where you initialize your app. You need to configure the GoogleReporter with UA-XXXXX-XX tracker ID.

import GoogleReporter

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        GoogleReporter.shared.configure(withTrackerId: "UA-XXXXX-XX")

        return true
    }
}

Usage

You can track any event you wish to using the event() method on the GoogleReporter. Example:

func didCompleteSignUp() {
    GoogleReporter.shared.event("Authentication", action: "Sign Up Completed")
}

In many cases you'll want to track what "screens" that the user navigates to. A natural place to do that is in your ViewControllers viewDidAppear. You can use the screenView() method of the GoogleReporter which works the same as event().

class BeerViewController: UIViewController {
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
	GoogleReporter.shared.screenView("Beer")
    }
}

Technical Notes

The GoogleReporter uses the native UserDefaults.standard to store a random UUID that uniquely identifies the user/install. Clearing or otherwise tampering with the UserDefaults may cause the user identifier to be lost and the GoogleReporter will generate a new unique identifier.

The GoogleReporter class is not thread-safe. To avoid bugs, always use the GoogleReporter.shared accessor from the same thread. I suggest using the main thread. The network call to log the data will still happen on a background thread.

Roadmap

We're planning to to add more functionality to easily interact with the Measurement Protocol. Still to be implemented:

Session tracking; start, end, duration.
Custom variable tracking for screenviews
