Xcode在启动时崩溃可能是由于开放项目太多

Question

我刚买了一台新Mac并下载了Xcode,所以一切都很新鲜.在第一次打开Xcode时,我不小心告诉它打开我的src /文件夹而不是/ src/myLatestProject所以我的预感是Xcode去了并试图打开我的src /目录中的每个项目(数百).它在海滩上停留了几秒钟然后坠毁了.现在的问题是,Xcode似乎记得我想要在app启动时打开多个项目,或者它正在尝试解析数百个git repos并且我陷入了开放/滩球/崩溃炼狱.如何重置Xcode的prefs,以便它不会尝试如此有用并打开我计算机上的每一点源代码？

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

Answer 1

不确定哪一个修复了它但是我在终端中运行了以下内容,现在再次运行:

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:请注意,这可能会删除其他首选项,如键绑定,因此如果您对xcode环境进行了大量自定义,请注意.

Answer 2

打开查找程序并转到以下路径并删除创建它们的文件夹,这些是我们在xcode中暂时打开任何项目时创建的文件夹:

/Users/MyMac/Library/Developer/Xcode/DerivedData/
