# NSMainCameraUsageDescription

A message that tells people why the app is requesting access to the device’s main camera.

## Discussion

The system uses this string to tell someone why your app requests permission to use the main camera.
In visionOS 2-2.3, the system uses the value of [`NSEnterpriseMCAMUsageDescription`](/documentation/BundleResources/Information-Property-List/NSEnterpriseMCAMUsageDescription) instead.

For information about using the main camera in your visionOS app, see <doc://com.apple.documentation/documentation/visionOS/accessing-the-main-camera>.

> Important:
> This key is required if your app uses APIs that access the device’s main camera.
