Without more details I couldn't be able to help you.

Do you keep weak references of the reactions selector?

For this kind of issue I suggest you to use stackoverflow, you'll have help faster.

@yannickl Hey Yannick, this is happening on iPhone X as well (not on iPhone 7 Plus though).

class HomeCell: UITableViewCell {

    var postID: Int?
    let reactionIDs = ["like", "love", "haha", "wow", "sad", "angry"]

    var reactionDelegate: HomeCellDelegate?

    @IBOutlet weak var profileImageView: UIImageView!
    @IBOutlet weak var titleLabel: UILabel!
    @IBOutlet weak var photoImageView: UIImageView!
    @IBOutlet weak var buttonsView: UIView!
    @IBOutlet weak var usernameLabel: UILabel!

    @IBOutlet weak var containerView: UIView!
    @IBOutlet weak var reactionButton: ReactionButton!

    // We have to know what the last focused reaction was, since selectorReaction is null at the beginning
    private var lastFocusedReaction: Reaction?

    override func awakeFromNib() {
        super.awakeFromNib()

        containerView.layer.cornerRadius = 20
        containerView.layer.shadowOpacity = 0.2 // opacity, 20%
        containerView.layer.shadowColor = UIColor.black.cgColor
        containerView.layer.shadowRadius = 2 // HALF of blur
        containerView.layer.shadowOffset = CGSize(width: 0, height: 2) // Spread x, y
        containerView.layer.masksToBounds =  false
        setupReactionButton()
    }

    private func setupReactionButton() {
        //let likeReaction = Reaction(id: "like", title: "Like", color: .blue, icon: #imageLiteral(resourceName: "like"))
        let reactionSelector = ReactionSelector()

        reactionButton.reaction = Reaction.facebook.like
//        reactionSelector.feedbackDelegate = self

        reactionSelector.reactions = Reaction.facebook.all

        // React to reaction change
        // This one takes a value from ReactionSelector
        reactionButton.addTarget(self, action: #selector(reactionChanged), for: .valueChanged)
        // And this one from ReactionButton
        reactionButton.addTarget(self, action: #selector(reactionChanged), for: .touchUpInside)

        // To attach a selector
        reactionButton.reactionSelector = reactionSelector

        // The last focused reaction is empty, so we'll make it the first of the reactions
        lastFocusedReaction = reactionSelector.reactions.first
    }

    override func layoutSubviews() {
        super.layoutSubviews()
        buttonsView.roundCorners(corners: [.bottomLeft, .bottomRight], radius: 20)

        profileImageView.layer.cornerRadius = profileImageView.frame.height / 2
        profileImageView.layer.masksToBounds = true
    }

    @objc func reactionChanged(_ sender: AnyObject) {
        guard let reaction = self.reactionButton.reactionSelector?.selectedReaction else {
            // No reaction here. This happens when tapping the button.
            // We'll use the selected state to know if the content was liked or unliked (or other reaction).
            if let reaction = lastFocusedReaction, let index = reactionIDs.index(of: reaction.id) {
                if (reactionButton.isSelected) {
                    reactionDelegate?.didChangeReaction(reactionNumber: index + 1, postID: postID ?? 0)
                    // The current reaction was selected (liked, loved, wow-ed, etc.)
                    // Here you'll want to inform the delegate that a reaction was chosen
                }
                else {
                    // The content was unliked, un-haha-ed, un-wow-ed, whatever.
                    // Check lastFocusedReaction for the correct reaction that was deselected.
                    // Here you'll want to inform the delegate that a reaction was chosen
                    reactionDelegate?.didChangeReaction(reactionNumber: 0, postID: postID ?? 0)
                }
            }

            // Nothing to do here.
            return;
        }

        lastFocusedReaction = reaction

        // Reaction was selected through ReactionSelector()
        if (reactionButton.isSelected) {
            if let lastFocusedReaction = lastFocusedReaction, let index = reactionIDs.index(of: lastFocusedReaction.id) {
                reactionDelegate?.didChangeReaction(reactionNumber: index + 1, postID: postID ?? 0)
            }
            // Here you'll want to inform the delegate that a reaction was selected
        }
        else {
            // Here you'll want to inform the delegate that a reaction was de-selected
            reactionDelegate?.didChangeReaction(reactionNumber: 0, postID: postID ?? 0)
        }
    }
}

This is the line that gives the error:

    private static func imageWithName(_ name: String) -> UIImage {
      return UIImage(named: name, in: .reactionsBundle(), compatibleWith: nil)!
    }

This is a little weird, would you mind taking a look at the code? It looks like the app can't find the reactions bundle.

@csr thank you for reporting this. Is it reproductible on the simulator? It happens every time with the iPhone X (and only with the iPhone X in your case)?

How do you import the library? Using Cocoapods?

[csr]

we’re importing it with CocoaPods, yes it works on the simulator fine, just not on iPhone X.
