I’ve just made available another ASObjC sample project. This one shows the use of a table, implemented via an array controller and bindings. It doesn’t do anything productive, but it does it with very little code (more than strictly necessary, as it happens). There’s only one line that uses ObjC code.
The notes are sparse, but if you open MainMenu.xib in Interface Builder, many of the interface widgets have explanatory tool tips to explain the various bindings.
Those lamenting the passing of ASStudio might note the use of a search field, and the code needed to implement it.
And apologies for the shamelessly promotional nature of the project.
