Answer 1

After trying almost everything that i found can filter what exactly worked for me. Catalina 10.15.7 Xcode12.

1. Go to your home folder in finder and make sure to enable hidden files shift + command + . //yes its a **dot** key on keyboard
2. type dd if=/dev/zero of=/Users/<YOUR_USERNAME>/file bs=15m hit enter
3. monitor the size growth of file named file in finder
4. when it reaches something around 4-5GB kill the terminal with cntrl+c
5. open disk utility and check purge size start copying and pasting that huge file named file that you just made and monitor the purge size. When it will get 3-4GB its now time to delete all that huge files and empty trash.
6. restart
7. open terminal go to /library/developer/
8. delete all folder and files inside coreSimulator (this was the only resort for me)
9. go to /library/developer/xcode/deriveddata and delete all folders and files inside
10. empty trash

Go to App Store and update the Xcode.

Answer 2

Just run below two commands in your terminal:

cd ~/Library/Developer

rm -rf Xcode

Answer 3

The same here for Xcode 11.2. It is mandatory to have at least 28GB free.

removing different directories such us, caches, .eclipse, .julia directories to free up.

UPDATE: 24GB with lastest version: 11.2.1

Answer 4

Mine is a weird solution. I did not have storedownloadd folder previous solutions talked about and manually downloading was not a real solution(what about future updates)

I manually created storedownloadd In the following directory re-started App Store, although loader took forever(restarted MacBook hoping for a change) it started downloading :)

~/Library/Caches/storedownloadd

Answer 5

I solved it by upgrading MacOS as I'd have an old version installed. After a restart it magically had space :D (the same by the way)

Answer 6

Trying to update to xcode 11.3.1 today, was in the problem like this. However, I can confirm that the download starts right after free space reaches 24GB as per some of the comments above.

I did the following:
- remove ~/Library/Caches/storedownloadd
- remove ~/Library/Developer/Xcode/iOS DeviceSupport/
- remove some files inside ~/Library/Developer/Xcode/DerivedData
- remove other unused files
