您刚刚通过类初始化程序创建了控制器，要从情节提要中实例化它，您必须像下面这样

You just created controller by class initialiser, to instantiate it from storyboard you have to do like the following

func makeUIViewController(context: 
         UIViewControllerRepresentableContext<AssetsListView>) -> AssetsListViewController {
    let storyboard = UIStoryboard(name: "Main",     // < your storyboard name here
          bundle: nil)
    let assetsListVC = storyboard.instantiateViewController(identifier: 
          "AssetsListViewController")      // < your controller storyboard id here

    assetsListVC.taskID = taskID
    return assetsListVC

}
