【问题描述】：

我从应用程序的用户那里收到了有关 Xcode 管理器的这些崩溃报告。它在崩溃中没有显示我的任何代码行，看起来它在初始化时崩溃了。我不知道如何进行调试。你能帮忙吗：

【参考方案1】：

我遇到了类似的问题。就我而言，问题在于我更改了手表应用程序扩展名，因此它不包含下划线字符。在此之后，我经历了这次崩溃。

解决方案是，进入手表应用程序扩展的故事板文件，并在现有视图控制器的身份检查器中，我只是重新输入自定义类名的名称，模块会自动更新。在此之后，它起作用了。希望它也适用于您。

【讨论】：

重新输入可能会导致重新分配目标 - 这可能是修复它的原因。

【参考方案2】：

仅供参考。我遇到的问题就是其中一个令人尴尬的问题。

故事板启用了“从目标继承模块”。

但是，Apple 创建的默认布局将可执行文件放在单独的（扩展）目标中。

我需要取消选中该框，并明确引用我的扩展目标。

天啊！
