More or less. If you define an `extern (Objective-C)` class in D (once 
all my work is merged), you can use it and derive from it in Swift. If 
you define an `@objc` class in Swift you can use it from Objective-C 
and from D, but you can't derive from it.

Note that the Swift ABI isn't stable yet. So the above might change at 
some point.
