# beginInterruption()

Called after your audio session is interrupted.

## Declaration

```swift
optional func beginInterruption()
```

## Discussion

Discussion By the time this interruption arrives, your audio has already stopped. Your application may be suspended or terminated following an interruption—for example, if a user chooses to take an incoming phone call. Use this method to adjust the user interface, and to save application state, as necessary.
