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

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

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.

XCODE 12 UPDATE

On the tab:

  1. Click Xcode
  2. Preferences
  3. Locations -> Derived Data

You can access all derived data and clear by deleting them.

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 Update For remove particular project's DeriveData you just need to follow the following steps:

Go to Window -> Project:

enter image description here

You can find the list of project and you can either go the DerivedData Folder or you can direct delete individual Project's DerivedData

enter image description here

I am not working on Xcode5 but in 4.6.3 you can find DerivedData folder as found in the below image:

enter image description here

After clicking on Preferences..

enter image description here

You get this window

yes, safe to delete, my script searches and nukes every instance it finds, easily modified to a local directory

#!/usr/bin/env bash
set -o errexit
set -o nounset
set -o pipefail
IFS=$'\n\t'

for drive in Swap Media OSX_10.11.6/$HOME
do
   pushd /Volumes/${drive}  &> /dev/null
   gfind . -depth -name 'DerivedData'|xargs -I '{}' /bin/rm -fR '{}'
   popd &> /dev/null
done

 $ du -h -d=1 ~/Library/Developer/Xcode/*

shows at least two folders are huge:

 1.5G   /Users/horace/Library/Developer/Xcode/DerivedData
 9.4G   /Users/horace/Library/Developer/Xcode/iOS DeviceSupport

Feel free to remove stuff in the folders:

 rm -rf ~/Library/Developer/Xcode/DerivedData/*

and some in:

 open ~/Library/Developer/Xcode/iOS\ DeviceSupport/

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

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

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

The content of 'Derived Data' is generated during Build-time. You can delete it safely. Follow below steps for deleting 'Derived Data' :

  1. Select Xcode -> Preferences..

Step 1

  1. This will open pop-up window. Select 'Locations' tab. In Locations sub-tab you can see 'Derived Data' Click on arrow icon next to path.

Step 2

  1. This will open-up folder containing 'Derived Data' Right click and Delete folder.

Step 3

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.

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
