Xcode崩溃在启动可能由于太多的开放项目 [英] Xcode crashing on startup possibly due to too many open projects

问题描述

我刚刚得到一个新的Mac和下载Xcode，所以一切都是新鲜的。在打开Xcode第一次我不小心地告诉它打开我的src /文件夹而不是/ src / myLatestProject所以我的预感是Xcode去并试图打开我的src /目录（数百）中的每个项目。它beachballed几秒钟，然后坠毁。现在的问题是，Xcode似乎记得，我想要大量的项目在应用程序启动时打开，或者它试图解析数百git repos，我被困在打开/ beachball /崩溃炼狱。如何重置Xcode的prefs，所以它不会尝试如此有用和打开我的计算机上的每一个源代码？

I just got a new Mac and downloaded Xcode so everything is fresh. On opening Xcode for the first time I accidentally told it to open my src/ folder instead of /src/myLatestProject so my hunch is Xcode went and tried to open every project in my src/ directory (hundreds). It beachballed for a few seconds and then crashed. The issue now is that Xcode seems to have remembered that I want that multitude of projects opened at app startup or it's trying to parse hundreds of git repos and I'm stuck in open/beachball/crash purgatory. How can I reset Xcode's prefs so it won't try to be so helpful and open every bit of source code on my computer?

编辑：我已经确认它只有崩溃我的帐户。如果我创建一个测试用户并打开Xcode，一切都很好。

I've confirmed it's only crashing for my account. If I create a test user and open Xcode, everything is fine.

推荐答案

不知道是哪一个固定的，但我在终端运行以下，现在它再次工作：

Not sure which one fixed it but I ran the following in terminal and now it works again:

cd ~/Library
sudo rm -rf './Preferences/com.apple.dt.Xcode.plist' './Autosave Information/com.apple.dt.Xcode.plist'  './Autosave Information/Unsaved Xcode Document.xcworkspace' './Caches/com.apple.dt.Xcode'

警告：删除其他首选项（如键绑定），因此请谨防您对xcode环境进行了大量自定义。

WARNING: Note this may delete other preferences such as key bindings so beware if you have a lot of customization of your xcode environment.
