This helped me understand why I was having some trouble wrapping my head around some of the syntax of Objective-C. This is worth a read since, unfortunately, it looks like Apple is not moving away from Objective-C any time soon[^f1731].
[^f1731]: Despite [John Siracusa’s pleas](http://5by5.tv/hypercritical/14).
I might not develop an iOS application using this, but it could be helpful for experienced Java programmers using Objective-C for the first time[^f5048].
[^f5048]: I think it would be similar to learning HTML by doing something in the Dreamweaver GUI and then seeing what HTML the program writes in the “source view.”
