            TextMessagePresenterBuilder(
                viewModelBuilder: TextMessageViewModelDefaultBuilder(),
                interactionHandler: TextMessageHandler(baseHandler: self.baseMessageHandler)
            )
        ]
    ]
}

override func createChatInputView() -> UIView {
    let chatInputView = ChatInputBar.loadNib()
    self.configureChatInputBar(chatInputView)
    self.chatInputPresenter = ChatInputBarPresenter(chatInputView: chatInputView, chatInputItems: self.createChatInputItems())
    return chatInputView
}

override func viewDidLoad() {
    super.viewDidLoad()
    self.chatDataSource = self.myDataSource
}
