I've noticed a problem where Xcode won't even try to auto-complete in only one Swift source file in my project. I've tried to find i fthere's something particularly unique about the file, but the only thing noticeable is that it consists of 9 Structs and 1 Function — no Classes at all.
I'm curious if anyone else has noticed such a thing? All my other files in the Workspace auto-complete "reasonably" — sometimes auto-complete stops working until the project is re-indexed, etc., but otherwise it "works."
UPDATE: I've found that if I hammer on CTRL-SPACE about 30 times, I can get the auto-complete box to show up:
