Can I safely delete contents of Xcode Derived data folder

Question

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

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   It speeds up compiling  also eliminates this problem  xc-launch repo  Best launched using DTerm

I would say it s safe--I often delete the contents of the folder for many kind of iOS projects  this way  And  I haven t had any issues with builds or submitting to the App Store  The procedure deletes derived data and cleans a project s cached assets  for both Xcode 5 and 6   Sometimes  simply calling rm -rf on the Derived Data directory leaves a lingering file or two  but my script loops until all files are deleted

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 - gt  Preferences - gt  location - gt  click on small arrow button as i explain in my first answer    Xcode7 3 Update For remove particular project s DeriveData you just need to follow the following steps   Go to Window - gt  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
