I'm also interested in making native macOS apps. I have a lot of 
experience in Objective-C but I'm new at D. I'm a bit confused at 
what documentation to look at. In [1] I get the impression that 
support for creating instances is very rudimentary, but in [2] it 
looks much better with constructors mapped with @selector. What 
level of support is there in the latest DMD compiler?

Also, is there any support for creating macOS application bundles?
