# sessionControlsWillExitFullscreenAppearance(_:)

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

## Declaration

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

## Parameters

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

## Discussion

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(_:).
