Declaration
class NSPreviewRepresentingActivityItemOverview
An NSPreviewRepresentingActivityItem object provides a concrete implementation of the NSPreviewRepresentableActivityItem protocol. Use it to create shareable items for common types such as strings or images, or when you don’t want to adopt the NSPreviewRepresentableActivityItem protocol directly in your app’s objects. To share the item from your app, initialize the NSSharingServicePicker object with this object.
