ios 我可以安全地删除 Xcode Derived 数据文件夹的内容吗？

Can I safely delete contents of Xcode Derived data folder?

提问by Sam B

I am running low on disk space and checked through a third party utility that among other things that ~/Library/Developer/Xcode/DerivedData directory is taking about 22GB of disk space.

我的磁盘空间不足，并通过第三方实用程序进行了检查，其中 ~/Library/Developer/Xcode/DerivedData 目录占用了大约 22GB 的磁盘空间。

I searched stackoverflow and found this post

How can I safely delete in my ~/Library/Developer/Xcode/DerivedData directory?

如何在我的 ~/Library/Developer/Xcode/DerivedData 目录中安全地删除？

The accepted answer to this question suggests that I should not touch / remove folders from this directory. so what I did was

这个问题的公认答案表明我不应该从这个目录中触摸/删除文件夹。所以我所做的是

• Found an existing build project folder for an app that I have available on Appstore
• Deleted the folder from derived dir
• launched XCode 5
• Open that project
• Clean Build
• Tested and compiled it on a simulator
• ReArchived
• Everything worked. Nothing was broken.

• 为我在 Appstore 上提供的应用程序找到了一个现有的构建项目文件夹
• 从派生目录中删除了文件夹
• 推出 XCode 5
• 打开那个项目
• 清洁构建
• 在模拟器上测试和编译
• 重新存档
• 一切正常。什么都没坏。

Unless I missed something in that posts answer I want to make sure by asking experienced developers that if I delete all the folders from DerivedData it will not hurt me in building, testing and compiling those projects.

除非我在那个帖子的回答中遗漏了一些东西，否则我想通过询问有经验的开发人员来确保，如果我从 DerivedData 中删除所有文件夹，它不会在构建、测试和编译这些项目时伤害我。

Yes, you can delete all files from DerivedDatasub-folder (Not DerivedData Folder)directly.

是的，您可以直接删除DerivedData子文件夹中的所有文件(Not DerivedData Folder)。

That will not affect your project work. Contents of DerivedDatafolder is generated during the build time and you can delete them if you want. It's not an issue.

这不会影响您的项目工作。DerivedData文件夹的内容是在构建期间生成的，您可以根据需要删除它们。这不是问题。

The contents of DerivedDatawill be recreated when you build your projects again.

DerivedData当您再次构建项目时，将重新创建的内容。

I purge derivedData often enough that I have an alias for it. It can fix build problems. I have the following in /Users/Myusername/.bash_profile

我经常清除衍生数据，以至于我有一个别名。它可以解决构建问题。我在 /Users/Myusername/.bash_profile 中有以下内容

alias purgeallbuilds='rm -rf ~/Library/Developer/Xcode/DerivedData/*'

Then in terminal, I type purgeallbuilds, and all subfolders of DerivedData are deleted.

然后在终端中，我输入 purgeallbuilds，并删除 DerivedData 的所有子文件夹。

Just created a github repo with a small script, that creates a RAM disk. If you point your DerivedData folder to /Volumes/ramdisk, after ejecting disk all files will be gone.

刚刚用一个小脚本创建了一个 github repo，它创建了一个 RAM 磁盘。如果您将 DerivedData 文件夹指向/Volumes/ramdisk，弹出磁盘后所有文件都将消失。
