Autocomplete is there. Also you have the ability to create your own micros that you can use to build skeletons (like a function, or a loop). I'm not sure about itegrated docs. You'll probably get a brief pop-up (hit-or-miss), but nothing like XCode's inline docs.
FYI: Docs are fully integrated and appear for example together when moving through the list of autocomplete suggestions. Very similar to XCode's inline docs. Alternatively, you can press Ctrl and every function call, class definition and so on becomes a link to the source code defintion of that function or class, respectively. Such are manifold possibilies for tool support in statically typed languages.
