Binding code seems to be unnecessary

First off, thanks for this step-by-step explanation, it saved me a bunch of trial and error. I downloaded the code, but it's Swift 3 and I have Xcode 9, so I couldn't run it. Sill, I followed the instructions to get everything working.

I wanted to mention that I didn't have to do the code as you described to get the table view's sort descriptors bound to the array controller. I just went to the table view bindings, checked the box next to Sort Descriptors, made sure the array controller was selected in the popup and then put "sortDescriptors" in the Controller Key field. That, combined with setting the Sort Key for each column, made the magic happen.

So you may be able to cut out a bunch of the explanation around this and just have people bind them directly in IB.

I haven't worked on this for a while so you are most probably correct. I did receive some info a while back that Apple was looking at making this easier so what you see is likely where they went with it.
