Anything’s better than the current Xcode autocomplete. My pet peeve is it will try to autocomplete any string you start typing with just random crap it thinks you might want in a string.
I think all autocomplete solution are crappy, no matter how sophisticated the AI. It is surprising how often the obvious choice is wrong, but it often just is. I deactivated it. Generating some code is fine, but I now prefer the deterministic autocomplete for my types I have available in my current context.
I just want it to fill in the names of function and variables and enums etc. just stuff that is sometimes hard to keep in your head but such a small suggestion it doesn’t mess up your line of thinking.
