Friends list is not displaying friends in Ribbit app

Have gone over and over this video. I can not get the friends to show up on the friends list. I have no idea what is could be, I have gone over this video 3 time and have not found any issues with my code.

here is the video: http://teamtreehouse.com/library/build-a-selfdestructing-message-iphone-app-2/relating-users-in-parsecom/displaying-our-list-of-friends

and here is my code

FriendsViewController.h 

#import <UIKit/UIKit.h>
#import <Parse/Parse.h>

@interface FriendsViewController : UITableViewController
@property (nonatomic, strong) PFRelation *friendsRelation;
@property (nonatomic, strong) NSArray *friends;

@end

#import "FriendsViewController.h"

@interface FriendsViewController ()

@end

@implementation FriendsViewController

-(void)viewDidLoad
{

    [super viewDidLoad];
    self.friendsRelation = [[PFUser currentUser] objectForKey:@"friendsRelation"];
    PFQuery *query = [self.friendsRelation query];
    [query orderByAscending:@"username"];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (error) {
            NSLog(@"Error %@ %@", error,[error userInfo]);
        }
        else {
            self.friends = objects;
            [self.tableView reloadData];
        }
    }];



}






#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    // Return the number of rows in the section.
    return [self.friends count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    PFUser *user = [self.friends objectAtIndex:indexPath.row];
    cell.textLabel.text = user.username;

    return cell;
}
