问题描述
我的磁盘空间不足并通过第三方实用程序检查了〜/ Library / Developer / Xcode / DerivedData目录占用了大约22GB的磁盘空间。
我搜索了stackoverflow并发现了这篇文章
你可以找到项目列表，你可以去 DerivedData 文件夹，也可以直接删除单个Project的 DerivedData
我不是在使用Xcode5，但在4.6.3中你可以找到 DerivedData 文件夹，如下图所示：
点击偏好设置..

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.
I searched stackoverflow and found this post
How can I safely delete in my ~/Library/Developer/Xcode/DerivedData directory?
The accepted answer to this question suggests that I should not touch / remove folders from this directory. so what I did was
- 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.
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.
Yes, you can delete all files from DerivedData sub-folder (Not DerivedData Folder) directly.
That will not affect your project work. Contents of DerivedData folder is generated during the build time and you can delete them if you want. It's not an issue.
The contents of DerivedData will be recreated when you build your projects again.
Xcode8+ Update
From the Xcode8 that removed project option from the window tab so you can still use first way:
Xcode -> Preferences -> location -> click on small arrow button as i explain in my first answer.
Xcode7.3 UpdateFor remove particular project's DeriveData you just need to follow the following steps:
Go to Window -> Project:
You can find the list of project and you can either go the DerivedData Folder or you can direct delete individual Project's DerivedData
I am not working on Xcode5 but in 4.6.3 you can find DerivedData folder as found in the below image:
After clicking on Preferences..
You get this window
