I tested with this app.
It is a real app. And autocompletion doesn't work at any place.

Actually, it works for locally defined symbols.
TheIDE is unable to resolve and autocomplete members of a class.
The app is just one cpp file less that 2K lines of code.

I believe this is a problem with libclang because I'm getting the same behavior with VIM and ccls Language Server.

I believe you need to use LibTooling instead of LibClang with TheIDE.
