struct Configuration

A structure that holds the identity of an app extension and process-related details. This type manages the configuration details you use to create an ``AppExtensionProcess`` structure. Create an instance of this type and initialize it with the identity of the app extension you want and a closure to run if the app extension terminates unexpectedly.
