*Extra credit* Displaying friend information

I'm trying to complete the extra credit assignment but I'm stuck when displaying a friend's information. This is my code on FriendsTableViewController.m I would like to know what am I missing or doing wrong when passing the friends data to the FriendsDetailViewController

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

    FriendDetailViewController *fvc = [[FriendDetailViewController alloc]init];
    fvc.friends = [NSMutableArray arrayWithArray:self.friends];
    PFUser *user = [self.friends objectAtIndex:indexPath.row];
        fvc.nameLabel.text = user.username;
    NSLog(@"%@",user.username);//displays username
    NSLog(@"%@",fvc.nameLabel.text);//displays null

//This is my code in FriendDetailViewController.m

  • (void)viewDidLoad { [super viewDidLoad]; if (self.user) { self.nameLabel.text = self.user.username; }else{ self.nameLabel.text = @"No data to display"; } } //displays "No data to display" ```
