第二个故事板无法正常工作？

如何解决第二个故事板无法正常工作？

因此，我正在尝试为我的项目使用第二个故事板作为入门屏幕。当我制作第二个情节提要板时，我放入了视图控制器，并在该第二个情节提要板的初始页面上放置了一个按钮。当我运行应用程序以测试按钮时，它没有响应。按钮本身不响应。甚至不打印（“单击”）。想知道它是否出现故障，因此我删除并制作了一个新的文件，对所有失败都进行了几次。我将继续进行另一个项目，制作另一个情节提要，并安装相同的方面（vc和按钮）。可以正常运行，这两个项目之间的唯一区别是我在场景委托中拥有的代码，该代码使应用程序可以在启动屏幕上启动。 和Im实际上使用了两个情节提要，而不是引用同一情节提要中的两个vc。

所以我在想这个问题是由代码引起的吗？任何帮助将不胜感激。

这是完整的场景委托代码。 View Controller代码无关紧要，因为它们只有按钮。
