The fact that I had to write so little code is a tribute to two things: the design of Apple APIs is very clean; and Ruby integration with ObjectiveC runtime is almost perfect.
Doing a web browser with XCode is equivalent to the early 90’s ‘Hello world’.
One interesting thing. I’m almost sure that I can reuse the same NIB file with a CamelBones project. I’ll try it next week and write the same app with it.
