I'm afraid you'll have to provide a bit more context. Do you have a specific question that someone could answer? Are you talking about building or installing? For building, the standard process is simple. Xcode > Product > Archive. There is no step two. For distribution, you can choose the Mac App Store or direct distribution. If you choose the Mac App Store, you're done with the installer package at that point. For direct distribution, you'll still need to zip the resulting app. You can do that in the Finder with control-click or double-click and choose Compress. Of course, if you're more of a masochist, there are many, many suggestions from the internet on how to make the process more difficult. You're correct that those procedures can get Kafkaesque in no time. But you don't have to do it that way if you don't want. And if you don't like those procedures, then I don't see the point of attempting them.
