A set of methods that you use to customize the position and animation of a share sheet, and to be notified whether the item is successfully shared.

```

[`NSSharingService.SharingContentScope`](/documentation/AppKit/NSSharingService/SharingContentScope)

The sharing scope constants specify the nature of the things you are sharing.
