# returnToCall(requestID:)

Requests that framework return to the FaceTime call, in order to resume the live assistance request.

```
@MainActor static func returnToCall(requestID: UUID)
```

## Discussion

Use this method when the framework launches your app in order to satisfy a request from your extension for the person using the app to sign in or provide other information. After your app collects the needed information, call this method from inside the <doc://com.apple.documentation/documentation/SwiftUI/View/onContinueUserActivity(_:perform:)> (SwiftUI) or <doc://com.apple.documentation/documentation/UIKit/UIApplicationDelegate/application(_:continue:restorationHandler:)> (UIKit) method where you handle the activity type [`containerAppLaunchActivityType`](/documentation/LiveCommunicationKit/LiveAssistance/containerAppLaunchActivityType). For the parameter `requestID`, fetch the value of [`containerAppLaunchRequestIDKey`](/documentation/LiveCommunicationKit/LiveAssistance/containerAppLaunchRequestIDKey) from the <doc://com.apple.documentation/documentation/Foundation/NSUserActivity/userInfo> dictionary of the <doc://com.apple.documentation/documentation/Foundation/NSUserActivity> sent to the launch method.

This method returns immediately. After you call it, the system foregrounds the FaceTime call and invokes the extension’s [`resumeRequest(_:)`](/documentation/LiveCommunicationKit/LiveAssistanceExtension/resumeRequest(_:)) to indicate that the container app has finished its work and the extension can continue setting up live assistance.

If the system doesn’t recognize `requestID` — possibly because the call ended or the person canceled the request — the framework silently ignores `returnToCall(_:)`. The container app doesn’t need to perform any clean-up work in this situation.
