The friends list no longer sorts alphabetically

Here is my code

CameraViewController.m 
#import "CameraViewController.h"
#import <MobileCoreServices/UTCoreTypes.h>

@interface CameraViewController ()

@end

@implementation CameraViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    self.friendsRelation = [[PFUser currentUser] relationForKey:@"friendsRelation"];
    self.recipients = [[NSMutableArray alloc] init];
}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    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];
        }
    }];
}
