Get started with Google Analytics

This quickstart shows you how to add Google Analytics to your app and begin logging events.

Google Analytics collects usage and behavior data for your app. The SDK logs two primary types of information:

  • Events: What is happening in your app, such as user actions, system events, or errors.
  • User properties: Attributes you define to describe segments of your user base, such as language preference or geographic location.

Analytics automatically logs some events and user properties; you don't need to add any code to enable them.

Before you begin

  1. If you're creating a new project, Add Firebase to your iOS project and follow the steps to set up Google Analytics for your project during project creation.

    If you have an existing project and did not configure Google Analytics, you can link Google Analytics to your project from the Integrations tab of your settings > Project settings.

  2. (Recommended). Add the AdSupport framework to your project to enable additional features such as audiences and campaign attribution.

Add the Analytics SDK to your app

  1. Add the dependency for Firebase to your Podfile: 
    pod 'Firebase/Analytics'
  2. Run pod install and open the created .xcworkspace file.
  3. Import the Firebase module in your UIApplicationDelegate:

    Swift

    import Firebase

    Objective-C

    @import Firebase;
  4. Configure a FirebaseApp shared instance, typically in your app's application:didFinishLaunchingWithOptions: method:

    Swift

    // Use Firebase library to configure APIs
FirebaseApp.configure()

    Objective-C

    // Use Firebase library to configure APIs
[FIRApp configure];


Start logging events

After you have configured the FirebaseApp instance, you can begin to log events with the logEvent() method.

Certain events are recommended for all apps; others are recommended for specific business types or verticals. You should send suggested events along with their prescribed parameters, to ensure maximum available detail in your reports and to benefit from future features and integrations as they become available. This section demonstrates logging a pre-defined event, for more information on logging events, see Log events.

The following example demonstrates how to log a recommended event to indicate a user has clicked on a specific element in your app:

Swift

Analytics.logEvent(AnalyticsEventSelectContent, parameters: [
  AnalyticsParameterItemID: "id-\(title!)",
  AnalyticsParameterItemName: title!,
  AnalyticsParameterContentType: "cont"
  ])

Objective-C

[FIRAnalytics logEventWithName:kFIREventSelectContent
                    parameters:@{
                                 kFIRParameterItemID:[NSString stringWithFormat:@"id-%@", self.title],
                                 kFIRParameterItemName:self.title,
                                 kFIRParameterContentType:@"image"
                                 }];

To view this event in the Xcode debug console, enable Analytics debugging:

  1. In Xcode, select Product > Scheme > Edit scheme...
  2. Select Run from the left menu.
  3. Select the Arguments tab.
  4. In the Arguments Passed On Launch section, add -FIRAnalyticsDebugEnabled.
