我有一个旧的 Objective-c项目,自2013年以来我没有接触过.

我已将Xcode升级到最新的8.2版本并重新打开项目(有很多警告).

通过打开项目,索引几乎立即开始,然后Xcode在几秒钟后崩溃.这是堆栈跟踪的相关(与我相关)部分.

这是崩溃的线程,给出的信息很少.

这些是我为解决问题而采取的步骤：

禁用自动索引.

defaults write com.apple.dt.XCode IDEIndexDisable 1

我尝试了很多东西,包括从头开始从git再次创建项目,或者只是清理派生数据文件夹.

然后我在堆栈跟踪中发现了这一点

XCCompilerSpecificationIBStoryboardLinker

所以,在绝望的举动中,我删除了故事板并再次添加了“添加文件”.我重新启用索引,一切都重新开始工作,不再崩溃.

问题是：我的故事板出了什么问题？什么导致XCode在索引时崩溃？

解决方法

从以下主题：

Xcode 6.1 crash on “Edit scheme”

https://forums.developer.apple.com/thread/19859

尝试以下可能会有所帮助：

尝试将Mac OS语言设置切换为英语(系统偏好设置 – >语言和地区),在首选语言中添加英语并将其设置为主要语言.

使用命令：

defaults delete com.apple.dt.Xcode
