Challenge task #3 of Finishing the User Interface

So the Challenge is:

Now, inside the block, set the 'blogPosts' NSArray property of this view controller using the following method: [BlogLoader getRecentPosts]. The super secret BlogLoader class will download an array of blog posts for us.

Can't seem to figure out what im missing... should the self.blogPosts property be set a different way?? i.e [NSArray ?????:[BLogLoader getRecentPost];

Here is my code...

'''Objective C

import "LeaderboardViewController.h"

@implementation LeaderboardViewController

  • (void)viewDidLoad { [super viewDidLoad];

    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0); dispatch_async(queue, ^{ self.blogPosts = [BlogLoader getRecentPost]; }); }

@end '''

you have an extra curly brace on the end that is causing an issue as well as misspelling getRecentPosts as getRecentPost. try:

dispatch_async(queue, ^{ self.blogPosts = [BlogLoader getRecentPosts]; });
