I am busy working on the Vision2-Cocoa implementation and have some nice additions for better interaction with Objective-C ready, the code is now void-safe and the Cocoa-Eiffel wrapper is much more complete. But more about that some other time. For now I just want to take a short break and present you the "New Cocoa Application Wizard" which I wrote yesterday.

This new wizard is similar to those for creating a new EiffelVision2 or WEL projects and should get you started right away. This wizard and the current Cocoa-Eiffel library will be available in a development version of EiffelStudio soon after 6.4 is out and will hopefully make it in the official version 6.5.

Further down are a couple of screenshots where you can see the new wizard. Note that the wizard, written in EiffelVision2, is already running with the new Cocoa backend, while the EiffelStudio window you can see in the background is still using the GTK+ implementation.

If you are interested in writing a graphical application on Mac OS X using Eiffel make sure you give the new Cocoa-Eiffel framework a shot.

The code for creating an application with a single window is pretty easy:
