推荐答案

这类崩溃的最常见原因是DerivedData目录损坏.您可以删除此目录(我们中的许多人经常这样做，只是为了使事情保持稳定).

The most common cause of these kinds of crashes is a corrupted DerivedData directory. You can delete this directory (and many of us do this regularly, just to keep things more stable).

• 打开Xcode
• 首选项
• 位置
• 派生数据"选项将告诉您目录的位置
• 删除该目录
• 尝试打开您的项目

就个人而言，我为派生数据"选择自定义"，并将其放在/tmp/xcode-build中.每次重新启动时，这都会删除该目录，并且比我要手动删除的目录更容易键入默认目录.

Personally, I select "Custom" for Derived Data, and put it in /tmp/xcode-build. This deletes the directory every time I reboot, and is easier to type than the default when I want to delete it by hand.

另一个常见问题:升级Xcode后，您通常需要重新启动.从Xcode 5开始，这个问题就不那么重要了，但是仍然值得尝试，尤其是当您从Xcode 4升级时.

One more common problem: you often need to reboot after upgrading Xcode. Since Xcode 5, that's been less of an issue, but it's still worth trying, especially if you're upgrading from Xcode 4.
