# activePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditions

The conditions that restrict camera switching behavior for the active primary constituent device.

## Declaration

```swift
var activePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditions: AVCaptureDevice.PrimaryConstituentDeviceRestrictedSwitchingBehaviorConditions { get }
```

## Discussion

Discussion For virtual devices with multiple constituent devices, this property returns the active restricted switching behavior conditions. This is equal to primaryConstituentDeviceRestrictedSwitchingBehaviorConditions except while recording using an AVCaptureMovieFileOutput that you configure with different restricted switching behavior conditions. Devices that don’t support constituent device switching return AVCapturePrimaryConstituentDeviceRestrictedSwitchingBehaviorConditionNone. This property is key-value observable.
