UINavigationBar Title with Image

UINavigationBarTitle+Icon.m

    // Icon
    UIImage *headerIcon = [UIImage imageNamed:@"store32"];
    NSTextAttachment *textAttachment = [[NSTextAttachment alloc] init];
    textAttachment.image = headerIcon;
    NSAttributedString *icon = [NSAttributedString attributedStringWithAttachment:textAttachment];
    
    // space between icon and title
    NSAttributedString *space = [[NSAttributedString alloc] initWithString:@" "];
    
    // Title
    NSAttributedString *title = [[NSAttributedString alloc] initWithString:self.navigationItem.title];
    
    // new title
    NSMutableAttributedString *attributedTitle = [[NSMutableAttributedString alloc] initWithAttributedString:icon];
    [attributedTitle appendAttributedString:space];
    [attributedTitle appendAttributedString:title];
    
    // move text up to align with image
    [attributedTitle addAttribute:NSBaselineOffsetAttributeName
                             value:@(10.0)
                             range:NSMakeRange(1, attributedTitle.length-1)];
    
    UILabel *titleLabel = [UILabel new];
    titleLabel.font = [UIFont fontWithName:@"HelveticaNeue" size:17.f];
    titleLabel.attributedText = attributedTitle;
    [titleLabel sizeToFit];
    self.navigationItem.titleView = titleLabel;

I'm trying to implement this code, but all I am able to get it to do is show '...' at the bottom left corner of the UINavigationBar. What is happening?
