I remember reading a rather silly fantasy book, back in the '90s. It was obviously written by a UNIX guy, and it featured a software geek that gets transported into a realm where magic works. He then started to build a foundation of spells, even giving them UNIX names like "Grep," and "Sed." It was all about how he built a powerful magic system, from scratch, starting with basic components, and combing them, into more ambitious components, and so on. Most of my published work is components; usually, Swift Package Manager packages. Each one is carefully written and documented, then tested like crazy. It means that I can leverage them, without a second thought, as to Quality, or features. Here's what I'm working on, now[0]. It still has a long way to go, but it's coming along nicely. It's a "swipeable" tab bar controller, so that iOS apps can behave like Android apps. I have been doing this by hand, in many of my latest apps, and I thought that it was a good candidate for commoditization. I'll spend a lot of time, testing and documenting it, so it will be a "drop in" module that I'll be able to use for future apps.
