Can’t update xcode after update to Catalina

After updating my Macbook to the latest OSX version Catalina, the xcode package wasn’t able to update anymore. After spending some time, this solution worked for me:

1. Remove the xcode package by dragging it from the Applications folder to Trash
2. In the Terminal, paste these two commands:
   rm -rf ~/Library/Developer
   rm -rf ~/Library/Caches/com.apple.dt.Xcode
3. Reboot your machine
4. Reinstall xcode from the App Store
