Swift 无法创建类'；（空）和#x27；迅速地

我已经添加了SideMenuController情节提要，从这里向MenuVC（sidemenu tableview）和Navigationcontroller添加了自定义segue

从Navigationcontroller到关系segue到rootviewcontroller再到HomeVC

我已经给了SignupVC初始视图控制器

我已经创建了自定义导航栏，附带菜单如下：

  func setUpNavigationBar(){
   
    let menuImageView = UIImageView.init(image: #imageLiteral(resourceName: "menu8"))
    menuImageView.tintColor = .darkGray
    menuImageView.frame = CGRect(x:0.0,y:0.0, width:25,height:25.0)
    menuImageView.contentMode = .scaleAspectFit
    menuImageView.widthAnchor.constraint(equalToConstant: 25).isActive = true
    menuImageView.heightAnchor.constraint(equalToConstant: 25).isActive = true
    menuImageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(menuClick)))
    let btnMenu = UIBarButtonItem(customView: menuImageView)
    
    self.navigationItem.setLeftBarButton(btnMenu, animated: true)
  }

 @objc func menuClick(){
    print("menu click...")
    SideMenuController.preferences.basic.menuWidth = self.view.frame.width*0.8
    if !(self.sideMenuController?.isMenuRevealed ?? false){
        self.sideMenuController?.revealMenu()
    }
}

如何为MenuVC.提供导航。。请帮忙。。我被卡住了

错误：

  func setUpNavigationBar(){
   
    let menuImageView = UIImageView.init(image: #imageLiteral(resourceName: "menu8"))
    menuImageView.tintColor = .darkGray
    menuImageView.frame = CGRect(x:0.0,y:0.0, width:25,height:25.0)
    menuImageView.contentMode = .scaleAspectFit
    menuImageView.widthAnchor.constraint(equalToConstant: 25).isActive = true
    menuImageView.heightAnchor.constraint(equalToConstant: 25).isActive = true
    menuImageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(menuClick)))
    let btnMenu = UIBarButtonItem(customView: menuImageView)
    
    self.navigationItem.setLeftBarButton(btnMenu, animated: true)
  }

 @objc func menuClick(){
    print("menu click...")
    SideMenuController.preferences.basic.menuWidth = self.view.frame.width*0.8
    if !(self.sideMenuController?.isMenuRevealed ?? false){
        self.sideMenuController?.revealMenu()
    }
}

由于未捕获的异常“NSInternalInconsistencyException”，正在终止应用程序，原因是：“无法创建类的序列”（null）”

在哪里以及如何定义SideMenuController？
