@import Contacts;
-(void)addToContactList
 {
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];

if (status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusRestricted) {

    UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:@"This app previously was refused permissions to contacts; Please go to settings and grant permission to this app so it can add the desired contact" preferredStyle:UIAlertControllerStyleAlert];

    [alert addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]];

    [self presentViewController:alert animated:TRUE completion:nil];

    return;

}

CNContactStore *store = [[CNContactStore alloc] init];

[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {

    if (!granted) {

        dispatch_async(dispatch_get_main_queue(), ^{

            // user didn't grant access;

            // so, again, tell user here why app needs permissions in order  to do it's job;

            // this is dispatched to the main queue because this request could be running on background thread

        });

        return;

    }



    // create contact



    CNMutableContact *contact = [[CNMutableContact alloc] init];

    contact.givenName = @"Test";

    contact.familyName = @"User";

    CNLabeledValue *homePhone = [CNLabeledValue labeledValueWithLabel:CNLabelHome value:[CNPhoneNumber phoneNumberWithStringValue:@"91012-555-1212"]];

    contact.phoneNumbers = @[homePhone];



    CNSaveRequest *request = [[CNSaveRequest alloc] init];

    [request addContact:contact toContainerWithIdentifier:nil];



    // save it



    NSError *saveError;

    if (![store executeSaveRequest:request error:&saveError]) {

        NSLog(@"error = %@", saveError);

    }

}];

 }
