我试过没有解决问题的方法有：

1. Quit Xcode
   Delete xcuserdata folder (Navigate to your project in Finder, right click on YourProject.xcworkspace, choose Show

package contents, then delete xcuserdata folder).
Delete DerivedData

1. 删除xcuserdata文件夹。

有没有好的解决方法！在线等！

Answer 1

IDEDiagnosticActivityLogMessage里的298行看看有没有问题

Answer 2

IDEDiagnosticFixItItem 在调用方法initWithFixItString:replacementLocation:创建实例的时候，参数fixItString为nil,所以Crash了

Answer 3

项目所在路径里面包含中文字符可能会导致Xcode崩溃，虽然不清楚其他项目为什么不会崩，但是将路径中包含的中文字符都改成英文之后就好了，你可以试试是否有效。

Answer 4

最简单的方法就是重新下载一个最新版的，注意要和系统对应的版本。我的系统10.12.5 Xcocd8.3.2一直在用，没有出现什么异常崩溃。
