I'm getting two responses every time my app runs.

Logging the response shows two identical response headers? Just curious. Here's my code:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.collectionView.backgroundColor = [UIColor whiteColor];
    [self.collectionView registerClass:[PhotoCell class] forCellWithReuseIdentifier:@"photo"];
    self.title = @"Photo Bombers";

    NSURLSession *session = [NSURLSession sharedSession];

    NSURL *url = [NSURL URLWithString:@"http://blog.teamtreehouse.com/api/get_recent_summary/"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    NSURLSessionDownloadTask *task = [session downloadTaskWithRequest:request completionHandler:^(NSURL * _Nullable location, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        NSLog(@"Response: %@", response);
    [task resume];

Could it be because the body of the text is coming in chunks, and it needs two responses to send it all?
