Take a look at this forum. There are at least weekly new proposals for features and improvements of the language. Most of those proposals are worked on by volunteers, who neither work at Apple nor are in the core team.
Sure this process needs a bit more time, but you can't just overlook the massive improvements Swift has made in the last years.
And yes...there is quite a clear vision for the future of Swift, shared by a member of the core team over here.
