下面的代码段

 func moveContactFromContainer(sourceContainer: CNContainer, destinationContainer: CNContainer){
        let predicate = CNContact.predicateForContactsInContainer(withIdentifier: sourceContainer.identifier)
        do{
            let results = try contactStore.unifiedContacts(matching: predicate, keysToFetch: keysToFetch as! [CNKeyDescriptor])
            for result in results{

                    print(result.givenName)
                    //print(result.phoneNumbers)
                    let mutableContact1 = result.mutableCopy() as! CNMutableContact
                    let saveRequest1 = CNSaveRequest()
                    saveRequest1.delete(mutableContact1)
                    do {
                        try contactStore.execute(saveRequest1)
                    } catch {
                        print("Error while deleting Contact \(error)")
                    }

                    let mutableContact = result.mutableCopy() as! CNMutableContact
                    let saveRequest = CNSaveRequest()
                    saveRequest.add(mutableContact, toContainerWithIdentifier: destinationContainer.identifier)
                    do {
