# AppExtensionProcess.Configuration

A structure that holds the identity of an app extension and process-related details.

```
struct Configuration
```

## Overview

This type manages the configuration details you use to create an [`AppExtensionProcess`](/documentation/ExtensionFoundation/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.

## Topics

### Creating the configuration structure

[`init(appExtensionIdentity: AppExtensionIdentity, onInterruption: () -> Void)`](/documentation/ExtensionFoundation/AppExtensionProcess/Configuration/init(appExtensionIdentity:onInterruption:))

### Responding to process interruptions

[`var onInterruption: () -> Void`](/documentation/ExtensionFoundation/AppExtensionProcess/Configuration/onInterruption)

The closure to run if the app extension’s process exits unexpectedly.

### Getting the app-extension details

[`var appExtensionIdentity: AppExtensionIdentity`](/documentation/ExtensionFoundation/AppExtensionProcess/Configuration/appExtensionIdentity)

The identifying information for the app extension you want to launch.
