Xcode crashes on launch
提问by Bernhard Miehl
I am developing an Application for iOS and I changed nothing in the Application. But at a restart of my Mac, Xcode crashes every time.
我正在为 iOS 开发一个应用程序，但我在应用程序中没有做任何更改。但是在我的 Mac 重新启动时，Xcode 每次都会崩溃。
Don't know if this is important, but my spotlight can't find any applications and also when I open the finder and using the shortcut cmd + shift + H I see a white window.
不知道这是否重要，但我的聚光灯找不到任何应用程序，而且当我打开查找器并使用快捷方式 cmd + shift + HI 时看到一个白色窗口。
Xcode isn't starting anymore and throws this error:

Could this be an issue due to Permissions conflicts?
由于权限冲突，这可能是一个问题吗？
ANSWER:
回答：
After I changed the rights from my OSX-Drive to everyone can write&read. Everything worked. But I knew that this is a temporary solution, so I decided to reinstall my MAC and everything was fine.
在我将我的 OSX 驱动器的权限更改为每个人都可以读写之后。一切正常。但我知道这是一个临时解决方案，所以我决定重新安装我的 MAC，一切都很好。

回答by chawki
If the delete of ~/Library/Developer/Xcode/DerivedData is not working for you, try this steps to remove xcuserdata:
如果删除 ~/Library/Developer/Xcode/DerivedData 对您不起作用，请尝试以下步骤删除 xcuserdata：
- open a Finder window and navigate to your project
- right-click on the .xcodeproj OR .xcworkspace file
- select Show Package Contents
- a new window appears
- delete a folder called xcuserdata
- 打开 Finder 窗口并导航到您的项目
- 右键单击 .xcodeproj 或 .xcworkspace 文件
- 选择显示包裹内容
- 出现一个新窗口
- 删除名为 xcuserdata 的文件夹
回答by Sunil Targe
I'll recommend deleting xcuserdata:folder from both of your .xcodeproj& .xcworkspacefile (open with Show Package Contents) and try again.
我会建议xcuserdata:从你的.xcodeproj&.xcworkspace文件中删除文件夹（用 Show Package Contents 打开），然后再试一次。
I hope this will work.
我希望这会奏效。

I had one where i selected a file that was quite large which crashed xcode when it tried to parse it. Then when i restarted it somehow it got set to load that file on start. Only way i saw was to temporarily rename the file that it was trying to load at start so it would load empty.
我有一个我选择了一个非常大的文件，当它试图解析它时它崩溃了 xcode。然后当我以某种方式重新启动它时，它被设置为在启动时加载该文件。我看到的唯一方法是临时重命名它在开始时尝试加载的文件，以便它加载为空。
