Unable to reset xcode theme/ color scheme

I accidentally changed the default theme "dracula" and now cannot change it back. i tried the method to add a new theme which would choose from original sources but it does not show the option for the same. any ideas? please refer to the image below for further details thanks in advance

Solution

I think Dracula is not a default Xcode theme from apple (I don't have it in my Xcode version 10.1 (10B61)), so maybe you need to re-install the original template.
