从第一个视图控制器导航到第二个视图控制器时出现错误信息.我的编码就像这个

let vc = LoginViewController(nibName: "LoginViewController", bundle: nil)
self.navigationController?.pushViewController(vc, animated: true)

问题是我总是收到这种错误信息

如何用语言切换UIViewcontroller到另一个？我正在创建一个新的空项目,并设置而不是使用故事板.UIViewControllerSwiftUINavigationcontroller

例如,我们在目标c中使用此代码来推送视图控制器

MyViewController *controller = [[MyViewController alloc] initWithNibName:@"MyViewController"    bundle:nil];
[self.navigationController pushViewController:controller animated:YES]

Swift的替代方案是什么？

任何帮助都可以提前感谢.

在objective-C中,为了从不同的故事板移动另一个视图控制器,我们将使用以下编码来实现我们想要的.

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Customer" bundle:nil];
HomeSummaryViewController *creaccVC = [storyboard instantiateViewControllerWithIdentifier:@"HomeSummaryViewController"];
[self.navigationController pushViewController:creaccVC animated:YES];

在swift版本中,请帮助我如何像Objective-C一样做？
