FirebaseAnalytics Framework Reference

FIRAnalytics(AppDelegate)

Provides App Delegate handlers to be used in your App Delegate.

To save time integrating Firebase Analytics in an application, Firebase Analytics does not require delegation implementation from the AppDelegate. Instead this is automatically done by Firebase Analytics. Should you choose instead to delegate manually, you can turn off the App Delegate Proxy by adding FirebaseAppDelegateProxyEnabled into your app’s Info.plist and setting it to NO, and adding the methods in this category to corresponding delegation handlers.

To handle Universal Links, you must return YES in [UIApplicationDelegate application:didFinishLaunchingWithOptions:].

  • Handles events related to a URL session that are waiting to be processed.

    For optimal use of Firebase Analytics, call this method from the [UIApplicationDelegate application:handleEventsForBackgroundURLSession:completionHandler] method of the app delegate in your app.

    Declaration

    Swift

    class func handleEvents(forBackgroundURLSession identifier: String, completionHandler: (() -> Void)? = nil)

    Parameters

    identifier

    The identifier of the URL session requiring attention.
    completionHandler

    The completion handler to call when you finish processing the events. Calling this completion handler lets the system know that your app’s user interface is updated and a new snapshot can be taken.

  • Handles the event when the app is launched by a URL.

    Call this method from [UIApplicationDelegate application:openURL:options:] (on iOS 9.0 and above), or [UIApplicationDelegate application:openURL:sourceApplication:annotation:] (on iOS 8.x and below) in your app.

    Declaration

    Swift

    class func handleOpen(_ url: URL)

    Parameters

    url

    The URL resource to open. This resource can be a network resource or a file.

  • Handles the event when the app receives data associated with user activity that includes a Universal Link (on iOS 9.0 and above).

    Call this method from [UIApplication continueUserActivity:restorationHandler:] in your app delegate (on iOS 9.0 and above).

    Declaration

    Swift

    class func handleUserActivity(_ userActivity: Any)

    Parameters

    userActivity

    The activity object containing the data associated with the task the user was performing.
