ios - remove - xcode derived data location




Can I safely delete contents of Xcode Derived data folder? (8)

XCODE 10 UPDATE

On the tab:

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

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

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.


XCODE 7.2 UPDATE

(Also works for 7.1.1)

  1. Click Window then Projects and then delete Derived Data.

Like this:

And then delete it here:


Hope that helps!


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.


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.


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..

  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.

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


XCode 8: To delete derived data for your current project:

Click Product menu

Hold Option key

Click Clean Build Folder


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

~/Library/Developer/Xcode/DerivedData
