This is a great point, and you're not wrong. This was a pretty unique case where I had a really clear idea in my head of what this would require from the get-go, and it was also meant to be a pretty quick, experimental little project. It seems to have struck a chord with some folks, so now I get to find out if my off-the-cuff approach is going to come back to haunt me soon.

As for SwiftUI, I think it'll be a slow and steady process for most of us. I've been a UIKit developer for the better part of a decade now, so I still feel most comfortable in that domain, but I think most folks acknowledge SwiftUI is the future. Although it's still a bit immature, I'm hoping to start shipping bits of SwiftUI here and there soon.
