Implementing new features in StoreKit — Before you read this story, note an updated version [as in code] can be found here. Subscriptions, Receipts, and StoreKit in iOS 14 The gold standard of in-app purchases and subscriptionsmedium.com Much of the buzz at WWDC2020 was given over to SwiftUI 2.0 and ARKit, so you should forgive yourself for missing a seismic change to the StoreKit framework — a change that will make…

A look at some different ways to link a class with a SwiftUI interface — I was playing around with SpriteKit, and it occurred to me that it might be a good exercise to remind myself of how many different ways I could link my SwiftUI code with my SpriteKit scene/class. I don’t present these in any order, preference, or recommendation; I show them in…

Some arguments to throw in there in your next interview as a senior developer — The world of work is rife with ageism, and the IT industry is undoubtedly one of the worse offenders, but is it justified? Join me for some honest thoughts on the subject. Why don’t older players in IT find new jobs; let’s talk about the issues and try and qualify…

Continuation of a paper about Emitter Nodes — The other week I published an article on emitter nodes, which would run under SceneKit or SpriteKit; both frameworks haven’t seen that much love in recent years; I finished up said article by developing a rudimentary SwiftUI version. It was a mini-project I enjoyed so much that I decided to…

Few companies can claim to have invented a verb or at least repurposed one. Verbs that were are the same across every language worldwide. The most famous is perhaps “Google.” You google something, meaning you look it up. Although there is an even earlier one more insidious than that, so…

Explosions are crafted mainly using EmitterNodes, available in SpriteKit, SceneKit and the CAAnimation framework. Nodes that the Apple documentation tells us…

Using SKSpriteKit with SwiftUI — I’m a fan of SwiftUI. I have been using it since its launch in 2019. In those five years, it has come a long way and had many updates, although some argue it isn’t ready for prime-time. One of those prime-time features not available within SwiftUI is the iOS physics…

How to integrate these frameworks — I published an article about future libraries coming to Swift in this paper. The gist of said presentation beyond the obvious was to suggest that said libraries are the most likely correct, efficient, and secure ways to achieve the task they have written to do, almost certainly more so than…

Let’s also use the SwiftUI Charts framework to get a better understanding of the values returned — Bon — so my muse is to build some hands-free apps, using FaceID capabilities of high-end devices like the iPhone 14 Pro and the iPad Pro. I tried to do tasks here and here with some success, but I still felt it was simply too hard to use and unreliable…
