Where should BrazeUI be imported in an iOS application?

Importing BrazeUI in the AppDelegate is essential for properly integrating with the Braze SDK in an iOS application. The AppDelegate serves as the central point of control and coordination for the application and handles application-level events such as launch, backgrounding, and transitioning to the foreground.

By importing BrazeUI here, you can ensure that the necessary setup and configuration for notifications, in-app messages, and other UI components provided by Braze take place at the start of the application lifecycle. This allows you to manage user engagement features effectively from the beginning and have consistent access to Braze's UI components throughout the app’s runtime.

Other areas such as UIViewControllers, SceneDelegate, or Storyboards are more focused on specific parts of the app's user interface or state management and are not ideal for handling global integrations like BrazeUI. The AppDelegate's role is more about application-wide setup, making it the most suitable place for such imports and configurations.
