Which method initializes the Braze SDK in an iOS application?

The choice that successfully initializes the Braze SDK in an iOS application is the method that incorporates the API key and configures it with an optional app group identifier. This method is specifically designed to set up the SDK with the necessary credentials to allow the app to communicate with the Braze service.

When you call Braze.startWithApiKey(_:appGroupId:), you are providing the essential API key that identifies your application instance within the Braze environment. This initial setup is crucial for enabling features such as user tracking, push notifications, and in-app messaging, all of which rely on the SDK being properly initialized with your unique API key.

Other methods may exist within the SDK, but they do not serve the purpose of initialization as clearly or completely as this one. For example, although methods like Braze.beginSession() and Braze.configure() may be part of the SDK’s workflow, they do not specifically perform the initialization process required for establishing a connection and setting up necessary configurations with the Braze backend. Thus, it is important to use the correct initialization method to ensure the application functions as intended with the Braze platform.
