Can I safely delete contents of Xcode Derived data folder?

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

What 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.

Xcode7.3 Update For remove particuler 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

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 a issue.

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

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
