I have contact data in my iOS app. I’ve created a CNMutableContact object and populated it with this data. Next, I created an NSItemProvider with this data and used it to create a UIDragItem. However, when I drag the contact view and drop it onto the Contacts app, the contact does not get imported. What could be the issue here?

UITableViewDragDelegate’s itemsForBeginning method.

First Attempt

func tableView(_ tableView: UITableView, itemsForBeginning session: any UIDragSession, at indexPath: IndexPath) -> [UIDragItem] {
        let contact = CNMutableContact()
        contact.givenName = "FIRST_NAME_LABEL"
        contact.middleName = "LAST_NAME_LABEL"
        contact.namePrefix = "MR"
        contact.note = "NoteContent"
        
        let dragItemProvider = NSItemProvider(object: contact)
        let dragItem = UIDragItem(itemProvider: dragItemProvider)
        
        return [dragItem]
    }

Second Attempt

func tableView(_ tableView: UITableView, itemsForBeginning session: any UIDragSession, at indexPath: IndexPath) -> [UIDragItem] {
        let contact = CNMutableContact()
        contact.givenName = "FIRST_NAME_LABEL"
        contact.middleName = "LAST_NAME_LABEL"
        contact.namePrefix = "MR"
        contact.note = "NoteContent"
        let dragItemProvider = NSItemProvider()
        dragItemProvider.registerDataRepresentation(forTypeIdentifier: UTType.vCard.identifier, visibility: .all) { completionHandler in 
        completionHandler(self.getVCardData(fromcontact: contact), nil)
        return nil
}
        let dragItem = UIDragItem(itemProvider: dragItemProvider)
        
        return [dragItem]
    }

func getVCardData(fromcontact contact: CNContact) -> Data? {
        do {
            return try CNContactVCardSerialization.data(with: [contact])
        } catch {
            print("Error converting contact to vCard: (error.localizedDescription)")
            return nil
        }
    }
