How to check if comment ( text) belongs to current user by uid

Question

So I am trying to create a function where users can delete their own comment/report others.

I've done this with the post so I assumed I would use the same method..which is grabbing the owner of the comments UID and check if that is the current user or not. If it is the current user then I will set up the alert controller to display "delete" else it'll be "report"

Here is a sample code of the post function that works correctly

  func handleOptionsTapped(for cell: FollowingCell) {

 guard let post = cell.post else { return }

        // If post belongs to current user display delete action sheet.. else report

if post.ownerUid == Auth.auth().currentUser?.uid {
            let alertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

            alertController.addAction(UIAlertAction(title: "Delete Post", style: .destructive, handler: { (_) in
                post.deletePost()

Also the post value in FollowingCell

 var post: Post? {
        didSet {
            guard let ownerUid = post?.ownerUid else { return }
            guard let imageUrl = post?.imageUrl else { return }


            Database.fetchUserWithUID(with: ownerUid) { (user) in
                self.profileImage.loadImage(with: user.profileImageUrl)
                self.username.setTitle(user.username, for: .normal)
                self.configurePostCaption(user: user)
            }
            postImage.loadImage(with: imageUrl)
            configureLikeButton()



            }
}

Here is the code I have for comments

   @objc func handleCommentTapped(for cell: CommentCell) {


         guard let comment = cell.comment else { return }

        // If comment belongs to the current user

        if comment.uid == Auth.auth().currentUser?.uid {
            print("this is my comment")

        } else {
            print("this is another users comment")
        }

    }

Also here is the code I have for the CommentCell

 var comment: Comment? {

            didSet {
                guard let comment = self.comment else { return }
                guard let uid = comment.uid else { return }
                guard let user = self.comment?.user else { return }
                guard let profileImageUrl = user.profileImageUrl else { return }

                Database.fetchUserWithUID(with: uid) { (user) in

                    self.profileImageView.loadImage(with: profileImageUrl)

                    self.configureCommentLabel()

                }
            }
    }

When I run the program I get a crash

Thread 1: EXC_BAD_ACCESS (code=257, address=0x1a2494098a1)

on the line guard let comment = cell.comment else { return }

I ran a breakpoint and everything is coming out to nil ( the text of the comment, the user's information who posted the comment, everything) Does anyone know how I can fix this? I am also using Active Label so I'm not sure if that is playing a factor not. Thanks!

Well, after 6 days of trying to figure out what I did wrong.. It appears all I forgot to add was

 cell.delegate = self

under cellForItemAt on the collection view function. So if anyone has this issue I hope this helps!

I love coding!
