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//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.
