I'm sure it's relatively easy for someone experienced with programming. I wrote the program back when I was learning Swift for the first time. There's a lot of counterintuitive shapes and graphics and knowledge you need. It's not linear algebra "difficult", but it does accumulate, until you're wondering why you're spending so much time drawing rectangles over text. I enjoyed the project, but it was definitely rife with a lot of strange behavior layered on top of each other. And Apple Documentation is a bit of a nightmare and basically useless in most cases.
