I think I wasn't clear in what I wrote. CoreFoundation is 
implemented in C, but CF objects aren't really an interface to C, 
but memory objects that (may) provide a toll free bridge to 
NSObject ARC protocols. Thus supports ARC by recasting a pointer 
rather than wrapping or conversion.

My point was more that in order to interface well with Swift I 
should generate objects that are toll free castable to ARC 
objects when I allocate. But I don't want that in my C++ code 
anyway, so therefore I might as well have a Objective-C++ layer 
between Swift and C++ on iOS.

I don't want lots of raw C malloc or C++ objects on the Swift 
side...

As Jacob pointed out, that does not work on Linux, but I am ok 
with C interfaces to C++ code on Linux.

iOS is different since so many OS calls _requires_ Objective-C 
function calls, so on iOS you often need to mix Objective-C and 
C++ (or whatever language you use).
