My most recent decades have been spent writing programs on Windows computers using the C++ programming language. The transition to programming an iPhone app on an Apple computer using Objective C was daunting. I believe the story of how I fared might be a little interesting to other programmer types considering the same type of leap. (And along the way I hit on one really, really useful paradigm that I think “sealed the deal” and would like to recommend to others.)
This post is “A Progression of Prototypes (or, “The-Idea-That-Sealed-The-Deal”).”
