ios - libc++abi.dylib : terminating with uncaught exception of type NSException without the regular error message

Question

我的应用程序因上述错误而崩溃。我检查了 swift 文件和 Storyboard之间的所有连接，似乎没有任何问题。此外，调试器似乎没有打印错误消息。这就是它给我的:

崩溃时突出显示的行可以在下面的链接中找到(为了以防万一，我截取了整个屏幕的屏幕截图，我不确定这是否有任何用处):

当您抛出异常并且没有人捕获该异常时，就会发生这种情况。 Objective C 和 C++ 异常使用相同的异常机制。尝试设置异常断点以捕获抛出的异常。这将向您显示谁抛出了未被捕获的异常。
