This seems to be quite a moving target. Based on past solutions, I was able to dig in figure out why this was broken (again).

In `Objective-C.tmbundle/Support/lib/docset_query.rb`, I had to change line 10 from

DOCSETS = Dir.glob("/Developer/Documentation/DocSets/*.docset”)

to

DOCSETS = Dir.glob("/Library/Developer/Shared/Documentation/DocSets/*.docset”)

Anyone else run into this?
