刚开始时，我在XCode中编写了一些（iOS）代码。看起来是IDE的一部分。崩溃日志说，IDE有一个NSRangeException。任何想法如何找到问题或重置，所以我回去？Xcode 8.1和8.2.1在启动时崩溃
我已清除此项目的派生数据并再次启动Xcode。它显示一秒钟然后崩溃。当我查看派生的数据文件夹时，它看起来像Xcode开始创建/index/debug/iphonesimulator10.1-x86_64/.xcindex/db.xcindexdb ...文件，然后在该过程中崩溃。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。
我试着回滚到之前版本的project.pbxproj，仍然有相同的崩溃问题。而Xcode只在这个项目上崩溃。我可以打开其他人。
更新：我升级到Xcode 8.2.1，仍然有相同的问题。我使用Pods，这意味着我正在使用工作区。不知道这是否导致任何问题。
这是可爱的碰撞报告。

@ Anbu.Karthik谢谢。但这是Xcode因苹果代码而崩溃，而不是我的。这个堆栈跟踪属于Xcode。 –
其他项目如何？只有在打开指定的项目时才会崩溃？ – nynohu
