Example runs only on 10.9

Is it by intention to run only on a not released Xcode version so far? I can make some build changes, but even the MainMenu.xib is in the new interface builder format.

You should state that requirement in your README file.

I do apologize for that. The reason is that I do not have Xcode 4 at the comment.

However, the MainMenu.xib is indeed just empty, all the view creation and configuration codes are located in AppDelegate.m.

A workaround for now is to create a new Cocoa project and replace the application delegate with AppDelegate.m.
