Last night I've upgraded my iPod Touch to the latest iPhone OS 3.0 and its corresponding SDK. The OS upgrade went smoothly. However for the SDK, what I had done was not working when I switch the include path to use the 3.0 SDK because it also required GCC 4.2 (by default it is GCC 4.0).

Here it is: my first graphical iPhone/iPod Touch application entirely written in Eiffel using EiffelStudio:

Nothing really fancy but it shows that it is doable. At the moment, you can test your Eiffel applications using either the iPhone Simulator or the actual device.

I was lucky to get my hands on an iPod Touch. The first thing I did was to install SSH, gcc, subversion, vim, gdb et voila! Checked out the source of the Eiffel Software runtime. Tonight, I'll compile the runtime and run our regression test suite on it to make sure everything works properly.

When this is done, I'll look at how to use Eiffel for iPhone/iPod Touch development.
