Xcode 8.1&；8.2.1启动时的崩溃

这是在我用XCode编写一些（iOS）代码时发生的。看起来是IDE的一部分。崩溃日志显示IDE有一个异常。有没有办法找到问题或重新设置以便我回去

我已经清除了这个项目的派生数据，并再次启动了Xcode。它会显示一秒钟，然后崩溃。当我查看派生数据文件夹时，它看起来像是Xcode开始创建/index/debug/iphonesimulator10.1-x86_64/.xindex/db.xcindexdb。。。文件，然后在此过程中崩溃。所以可能与我在第一次崩溃时运行的模拟器有关，但我没有使用它

我试图回滚到project.pbxproj的早期版本，但仍然存在相同的崩溃问题。Xcode只在这个项目上崩溃。我可以很好地打开其他的

更新：我升级到Xcode 8.2.1，但仍然存在相同的问题。我用的是豆荚，所以这意味着我在使用一个工作空间。不确定这是否会导致任何问题

这是可爱的坠机报告

可能您可以将Xcode更新到最新版本，即：8.2.1.：）

如果我删除了我的Xcode项目文件夹中的“build”文件夹，那么启动Xcode它就可以工作了！（而不是Xcode用户库文件夹中的派生数据文件夹。）

• 右键单击文件.xcworkspace>ShowPackageContents
• 删除xcuserdata文件夹

请参见@Anbu.Karthik，谢谢。但这是因为苹果的代码，而不是我的。此堆栈跟踪属于Xcode。其他项目如何？仅在打开指定项目时崩溃？然后启用zombies并在不打开项目时检查onceDoes Xcode崩溃？直接启动Xcode？我更新到8.2.1（当前最新版本），但仍然存在问题。有趣的是，我还没有运行最新的。AppStore从未向我显示Xcode有更新。。。反正还是没有爱。。。
