Apple’s documentation for all sorts of things is in a sorry state lately. That includes mass “retiring” of perfectly good documentation for non-deprecated things with no replacement. I wouldn’t take missing or hard-to-find documentation for any specific thing as an indication that it’s deprecated. As far as I know, Objective-C++ is as supported as ever. That is to say, it’s not exactly a banner feature, but it works fine, and there’s no reason not to use it if it’s the best solution to your particular problem. I use it in a number of places, including to expose C++ code to Swift, which doesn’t interop directly with C++.
