使用标识符执行segue时的信号Sigabrt

Question

我正在使用Swift和Xcode创建一个应用程序。我最近在执行segue时收到了一个Signal Sigabrt。这是错误：

2015-12-24 20:53:10.748 Passroom[8174:378664] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<Passroom.DashboardViewController: 0x7f8043c55d40>) has no segue with identifier 'dashboard''

注意：我的应用名称只是我实际应用名称的替代品。 这是我的故事板：

我正在使用此代码执行segue：

self.performSegueWithIdentifier("dashboard", sender: self)

我该如何解决此错误？感谢您的帮助。
