Xcode content assist fails when booting from external drive?

I boot from an external drive. Content assist in Xcode seems to not work any more. Is that because it is blocked by the unavailability of predictive code completion?

I understand that predictive code completion does not work when booting from externals, and have asked (begged?) for details so that I can migrate to booting from an internal drive:

But would someone (anyone?) please confirm that other forms of content assist still work in Xcode 16 when booting from an external drive? (Then I'll continue looking for why it's not working in my case.)

(Separately, I'd love answers to my other posting so I can migrate to booting from the internal drive.)
