# sessionControlsWillExitFullscreenAppearance(_:)

Tells the delegate when a capture session’s controls are about to exit a fullscreen appearance.

```
func sessionControlsWillExitFullscreenAppearance(_ session: AVCaptureSession)
```

## Parameters

`session`

The capture session with controls that are exiting a fullscreen appearance.

## Discussion

When your app receives this callback, it should resume showing portions of the interface it hid when controls entered a fullscreen appearance.

The system calls this method before [`sessionControlsDidBecomeInactive(_:)`](/documentation/AVFoundation/AVCaptureSessionControlsDelegate/sessionControlsDidBecomeInactive(_:)).
