        //
        messageInputBar.sendButton.tintColor = UIColor(red: 69/255, green: 193/255, blue: 89/255, alpha: 1)
        scrollsToBottomOnKeybordBeginsEditing = true // default false
        maintainPositionOnKeyboardFrameChanged = true // default false

        // Refresh
        messagesCollectionView.addSubview(refreshControl)
        refreshControl.addTarget(self, action: #selector(ChatViewController.observeMessages), for: .valueChanged)

        // Customisation
        defaultStyle()
    }

    func defaultStyle() {
        let newMessageInputBar = MessageInputBar()
        newMessageInputBar.sendButton.tintColor = UIColor(red: 69/255, green: 193/255, blue: 89/255, alpha: 1)
        newMessageInputBar.delegate = self
        messageInputBar = newMessageInputBar

Do you use IQKeyboardManager ?

[nathantannar4]

^ I have seen this before and IQKeyboardManager can be a reason. If not, please try MessageKit 2.0

[pawankmrai]

Yes, that's correct.
It's due to IQKeyboardManager.
Thanks, @nathantannar4 @c941010623 for quick help.
