【问题描述】：
没有警告，当我单击故事板文件时，我的 xcode 应用程序突然开始崩溃。经过一番挖掘，我发现很多人说要这样做：
"Go to
/Library/Developer/CoreSimulator/Profiles/Runtimes
and remove the profiles in there. Restart Xcode and it should work!"
当我在 finder 中搜索此文件夹时，转到文件夹功能，它说找不到。其他人说要清除颜色选择器，但这仍然对我不起作用。 Xcode 在 beta 1 和 4（我有）中都崩溃了。我真的需要一些帮助。
更新此错误消息也会出现在警告通知中： 由于缺少入口点，场景无法访问，并且没有通过 -instantiateViewControllerWithIdentifier: 进行运行时访问的标识符。
这是崩溃时的弹出窗口：

【问题讨论】：
-
我认为：在问题中有答案“转到/Library/Developer/CoreSimulator/Profiles/Runtimes 并删除其中的配置文件。重新启动Xcode，它应该可以工作！” Library 文件夹应该是隐藏的。请检查一下
-
@AshishKakkad 但我没有那个文件夹
-
转到您的 Finder > 转到菜单（按 Alt）> 库
-
@AshishKakkad 当我点击 coreSimulator 时，没有配置文件的文件夹，只有“设备”
-
@AdrianB 我在崩溃时发布了错误。我无法包含整个内容，因为它超出了字符数限制
