我的应用在发布时崩溃

标签： ios xcode

由于某种原因，当我运行我的应用程序时，应用程序崩溃然后在Xcode中它将我带到应用程序委托。错误消息在顶部给我（其中“AppDelegate类：UIResponder，UIApplicationDelegate”是）。错误消息是“线程1：信号SIGABRT”。由于我只是编程方面的新手，我不知道这意味着什么，并且没有在网上找到任何帮助。以下是我在Xcode中获得的截图。这不是另一个问题的重复，因为我的问题是为什么Xcode将我带到app delegate并向我显示SIGABRT ERROR。我只是不知道在那之后应该做什么.FYI-我不知道在控制台中出现错误enter image description here

这就是我的控制台：
