Yes but what I got from the article was that 'you have to use Xcode and Xcode sucks/is a pain to use'. In my (limited) cross-platform dev experience you open Xcode to press 'run' so your app runs on device (and you can do this from the command line if you prefer) and to 'archive' which brings you through a wizard to upload your app. So you avoid all of the Xcode pain points.
