Answer 1

I solved problem with cell spacing on cell in CollectionView

    if let layout = messagesCollectionView.collectionViewLayout as? MessagesCollectionViewFlowLayout {
        layout.textMessageSizeCalculator.outgoingAvatarSize = .zero
        layout.textMessageSizeCalculator.incomingAvatarSize = .zero
        layout.sectionInset = UIEdgeInsets(top: -10, left: 0, bottom: -5, right: 0)
        layout.minimumInteritemSpacing = 0
        layout.minimumLineSpacing = 0
    }
