ios - 由于未捕获的异常 'NSInvalidArgumentException' 而终止应用程序，原因 : '-[SWRevealViewController revealToggel:]

Question

我正在学习有关使用 Swift [开发 iOS 应用程序 (Swift)] 创建 iOS 应用程序的 Apple 教程，并且我完全按照原样执行了每个步骤。这个应用程序一直在模拟器中完美运行，但突然开始抛出 SIGABRT 错误(我做了一个简短的研究以了解 SIGABRT(信号中止)错误是什么，我什至找到了其他一些答案，但似乎没有人解决我的问题)。

控制台输出:

打字错误？应该是 revealToggle...
