ACAccount Unrecognized selector sent to instance(NSInvalidArgumentException)

Question

I select one of the existing accounts. I want to pass another viewController this selected account. But i get this error --> "Unrecognized selector sent to instance"

Here my code:

select account on tableView:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    AccountsTableViewCell *selectedRow = [self.accountTable cellForRowAtIndexPath:indexPath];
    choosenAccount = selectedRow.twitAccount;
     [self performSegueWithIdentifier:@"selectAccount" sender: nil];

}

segue:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"selectAccount"]) {
         TwitterFollowersViewController *vc = (TwitterFollowersViewController *) segue.destinationViewController;
        vc.twitterAccount = choosenAccount;
    }
}

ViewController.h file:

@interface TwitterFollowersViewController : UIViewController
      @property (retain, nonatomic) ACAccount *twitterAccount;
@end

Check the class name in the storyboard, I think its UIViewController rather then TwitterFollowersViewController.
