# LiveAssistanceRequestError

An error thrown by a live assistance extension when handling a request.

## Declaration

```swift
enum LiveAssistanceRequestError
```

## Overview

Overview Throw this error from your implementations of prepareAssistanceRequest(_:) and resumeRequest(_:) to end requests that you can’t service. Throwing is terminal; the request ends immediately, although the person using FaceTime can initiate a new one. If your container app can resolve the situation by requesting further input, don’t throw an error. Instead, return LiveAssistanceRequest.Response.requiresUserInput(reason:) to give the person a chance to sign in or otherwise provide the needed information. note: This enumeration is not frozen. Code that switches over a LiveAssistanceRequestError must include an @unknown default block.
