线程1:运行在SIGABRT;0_abort_with_payload SWIFT4.1上的信号

Question

当我在我的iPhone6上运行我的应用程序时，我会收到这个错误，但是在模拟器上运行。在模拟器中，当我从AppDelegate转到RouteTableViewController时，我在AlarmAddEditViewController上得到线程1: SIGABRT错误。我添加了一个部分，让我选择一个路由，所以当选择行时，routeSegue将被执行，然后是当我在AppDelegate上得到错误时。我找不出为什么添加到AlarmAddEditViewController中会扰乱代码。

这是在iPhone上运行它的结果：

这是在模拟器中运行的：

更新：

在将DataSource的出口连接到tableView并在iPhone上运行它时，将得到控制台输出：

模拟器中的问题是RouteTableViewController不是tableViewControlle，所以我解决了这个问题，现在routeSegue正常工作。现在，它也运行在iPhone上。谢谢帮助@ Shauket Sheikh。
