Can I safely delete contents of Xcode Derived data folder?
ios, xcode
Solution
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`:
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
Problem
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.
