setTitle not working within If statement (Like / Unlike feature)

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I'm working on displaying the number of "likes" a social media post has via .setTitle. I've confirmed I have the value of "count", however the if / else are not working.

I've encountered this problem while studying. Specially a tutorial to create a "clone" of Instagram. I've examined the provided code sample, comparing it to my own, however it looks identical - yet my results are different.

    func updateLike(post: Post) {

    let imageName = post.likes == nil || !post.isLiked! ? #imageLiteral(resourceName: "heart_inactive") : #imageLiteral(resourceName: "heart_active")

    likeImageView.image = imageName

    guard let count = post.likeCount else {

        return

    }

    if count != 0 {

        likeCountButton.setTitle("(count) likes", for: UIControl.State.normal)

    } else {

        likeCountButton.setTitle("Like this post first!", for: UIControl.State.normal)

    }



}

I expect the button title to be "Like this post first!" when count is 0, then "(count) likes" when count isn't 0

Right now the title is blank

guard will return when likeCount is nil , so try

if let count = post.likeCount , count != 0  { 

     likeCountButton.setTitle("(count) likes", for:.normal)

else 

    likeCountButton.setTitle("Like this post first!", for:.normal)

}
