Translating Java Into Swift

I’m working through the online book Crafting Interpreters, (which I highly recommend, if you’re curious about how such things are built). While going through it, I’m making a stab at translating the example code in the book (which is in Java) into Swift. This is not something I’m very familiar with, so I’m trying aContinue reading “Translating Java Into Swift”

Iterating through Strings in Swift

I recently decided to dive into a new bit of learning – creating my own software language interpreter. No, I’ve not gone stark raving mad due to COVID isolation, it is an interesting challenge that I wanted to understand better. Over a year ago, I remember Gus mentioning the process of creating an online bookContinue reading “Iterating through Strings in Swift”

The evolution of “safe” and “unsafe” in the Swift programming language

There’s been a lot of motion in the last four months of the evolution of the Swift programming language that I’ve been wanting, waiting, and hoping for. The language maintainers are tackling concurrency as a first-class construct in the language. I’m following along with the language evolution proposals in the forums, and so far haveContinue reading “The evolution of “safe” and “unsafe” in the Swift programming language”

Combine and Swift Concurrency

Just before last weekend, the folks on the Swift Core Team provided what I took to be a truly wonderful gift: a roadmap and series of proposals that outline a future of embedding concurrency primitives deeper into the swift language itself. If you’re interested in the details of programming language concurrency, it’s a good read.Continue reading “Combine and Swift Concurrency”

The range operator and SwiftUI’s layout engine

This post is specific to Swift the programming language and SwiftUI, Apple’s newest multi-platform UI framework. If you’re not interested in both, probably best to skip past this… I was working on visualization code that leverages SwiftUI to see how that might work, and ran into a few interesting tidbits: playgrounds with SwiftUI works brilliantly,Continue reading “The range operator and SwiftUI’s layout engine”

Open apps with SwiftUI

Earlier this week, James Dempsey asked on twitter about who else was actively trying to build macOS apps using SwiftUI. I’m super interested in SwiftUI. A year ago, it spawned my own side-project into writing my own reference docs on Combine. Originally I had a vision of writing about Combine as well as SwiftUI. CombineContinue reading “Open apps with SwiftUI”

Exploring MultipeerConnectivity

A few weeks ago, I got curious about the MultipeerConnectivity framework available across Apple’s platforms. It’s a neat framework, and there are community-based libraries that layer over it to make it easier to use for some use cases: MultipeerKit (src) being the one that stood out to me. The promise of what this framework doesContinue reading “Exploring MultipeerConnectivity”

Continuous Integration with Github Actions for macOS and iOS projects

GitHub Actions released in August 2019 – I’ve been trying them out for nearly a full year, using beta access available the adventurous before it was generally available. It was a long time in coming, and I saw this feature as GitHub’s missing piece. Some great companies stepped into that early gap and provide excellentContinue reading “Continuous Integration with Github Actions for macOS and iOS projects”

How to make a SwiftUI component that draws a Shape with light

While I was experimenting with SwiftUI, one of the effects I wanted to re-create was taking a shape and making “stroke effects” on it. The goal was to create a SwiftUI component that could take an arbitrary path, apply this effect to the shape, and render it within the context of a larger SwiftUI view.Continue reading “How to make a SwiftUI component that draws a Shape with light”
