The projects page seems to be disappeared from Xcode 8. I used this page for deleting the derived data.

Any idea how can I delete derived data from within Xcode 8?

(Working in Xcode 11, 12, 13, 14, and 15)

You can go to File > Workspace Settings if you are in a workspace environment or File > Project Settings for a regular project environment.

Then click over the little grey arrow under Derived data section and select your project folder to delete it.

Click that button

The simplest and fastest way is the following (if you have not changed the defaults folder for DerivedData).

Open terminal and past the following:

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

As an additional beneficial option, you can also delete all app builds on all of your simulators by running the following (once you've quit running any simulators) xcrun simctl erase all. This doesn't clear the same stuff as derivate data obviously, but if you're trying to free up space this is another great option, as both take up quite a bit for old app builds.
You could also make this a terminal shortcut. See here
But this also deletes the folder itself! Is that not a problem?
@user5306470 it is not, XCode will recreate it when needed.
Make sure to append sudo in front to have admin access, if your problem persists.

Many different solutions for this problem. Most of them work as well. Another shortcut seems to be added as well:

Shift + alt + command ⌘ + K

Will ask you to:

Are you sure you want to clean the build folder for “MyProject”?

This will delete all of the products and intermediate files in the build folder.

In most cases this would be enough to solve your problems.

UPDATE

As of Xcode 9 you'll be able to access the Derived Data folder by navigating to

File -> Project Settings

or if you use a Workspace:

File -> Workspace Settings

And press the arrow behind the path: enter image description here

After press the arrow, dont forget to first quit the XCode, and after that delete that folder from finder
⌘⇧K will clean your projects build folder but ⌥⌘⇧K will clean it immediately without warning
I had to also close Xcode and reopen it in Xcode 15.3

In Xcode 8, all the derived data is automatically cleaned. If you want to do it by hand, go to Locations tab from the Preferences, locate project's derived data folder, and delete files related to the project.

In macOS 10.12 and later, Xcode cleans up stale derived data, precompiled headers, and module caches. (23282174)

But from what I observed, the same behaviour is typical when using Xcode 8 on OS X 10.11.5/6

Do you have a reference to where this is specified?
is there an official source that confirm this that it is automatically cleaned?
Automatically cleaned when?
Xcode 8 release notes say "In macOS 10.12 and later, Xcode cleans up stale derived data, precompiled headers, and module caches." I'm not sure how often derived data is considered "stale" though... developer.apple.com/library/content/releasenotes/DeveloperTools/…
@dmzza not sure to be honest, Apple doesn't explain when it does it.

With a bit more of text/context into this answer... this should be the one selected. Adding screenshots it's always a huge plus.
Note that it will say "Workspace Settings" if you're using a .xcworkspace file instead of an .xcproject file. Caught me off guard for a second
After click the arrow, quit the XCode, and after that delete folder from finder
Nicely explained. @Nazik
without these remarks this solution would not work, please add them to your answer

Method 1:

  • Close Xcode

  • Open Terminal and enter this command

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

Method 2:

  • Click on Xcode menu
  • Go to Preference
  • Select Locations (as shown in image)
  • Click on the arrow below the Derived Data (as shown in image).

It will bring you to the location of derived data and you can just delete it manually.

Note that if you get an error saying a subfolder of the derived data directory could not be deleted because it's not empty (even when you run with -rf), you need to quit XCode and your simulator and then try again to clear the derived data

Manual removal of derived data

If you want to remove derived data manually just run:

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

If you want to free up more disk space there's a few other directories you might want to clear out as well though.

Automatic removal of Xcode generated files

I have created a Bash script for removing all kinds of files generated by Xcode. Removing DerivedData content can be done by running:

./xcode-clean.sh -d

Another way to go to your derived data folder is by right click on your App under "Products" folder in xcode and click "Show in Finder".

This won't work if you've set your product to a different path -- for example, I set mine to build straight to ~/Applications, but keep the derived data in the default location.

Go to the root of the project using terminal and then paste the below mentioned line

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

Once it is executed, you can verify by going to Xcode > Preference > Locations -> Tap arrow shows ["DeriveData"] end point.

You don't need to go to the root of the project since the command uses an absolute path.

It may differ between versions of xcodes. Best approach is to go xcode preference page and from tab "Locations", directly open "Derived Data" directory.

DevCleaner on the Mac App Store did the trick for me!

Also looks useful for removing other cruft due to Xcode. Remember this is a 3rd party app so usual trust warnings apply.

To delete derived data in Xcode 8, follow below steps:

  1. Open Xcode 8 and go to the "Preferences" menu.
  2. Click on the "Locations" tab.
  3. Look for the "Derived Data" section and click on the small arrow icon next to the path.
  4. This will open the "DerivedData" folder in Finder.
  5. Quit Xcode 8 to avoid any conflicts.
  6. Select all the folders inside the "DerivedData" folder and move them to the trash.
  7. Empty the trash to permanently delete the derived data.

It's a bit off-topic, but it has a bit of a binding part. If this error appears and then disappears, try this: Open the relevant UI tab by double-clicking, not single, that is, the file name opened in Xcode should not be italic, so it can be opened without booting. It's very strange but it happens that way.

For Xcode Version 8.2 (8C38), you can remove the projects completely (project name in Xcode, programs, data, etc.) one by one by doing the following: [Note: the instructions are not for just remove the project names from the Welcome Window]

Launch the Xocde and wait until the Welcome window is displayed. The projects will be shown on the right hand side (see below) Xcode Welcome Window

Right click the project you want to remove completely and a pop window [Show in Folder] jumps out; selec it to find out where is the project in the [Finder] (see below) Find the project folder

Right click the project folder in the Finder to find it’s path through [Get Info]; use path in the Info window to go to the parent folder, and go to there[Locate the project folder path] (see below)

Right click the Project Folder (e.g. DemoProject01) and Porject file (DemoProject01.xcodeproj) and select [Move to Trash] ; you will see that (a) the folder in finder is removed AND (b) the Project in the Xcode Welcome Window’s Project List is removed.

This has nothing to do with the deletion of Derived Data folder content.
