In the past couple of years, I’ve had the occasion to want to make an XCFramework – a bundle that’s used by Apple platforms to encapsulate binary frameworks or libraries – a couple of times. In both cases, the reason wasn’t that I didn’t want to ship the source, but because the source was fromContinue reading “Creating an XCFramework”

API Design decisions behind Lindenmayer in Swift
Procedural generation of art is fascinating to me. The scope of efforts that fall into the bucket of procedural generation is huge. Quite a lot of what you find is either focused on art or video games. Within procedural generation, there is a topic that really caught my eye, I think primarily because it wasn’tContinue reading “API Design decisions behind Lindenmayer in Swift”
Adding DocC to an existing swift package
During WWDC 21, Apple announced that they would be open sourcing documentation tooling (DocC) that’s used to build and provide documentation within Apple. At the tail end of October 2021, the initial version of DocC was released — available on Github, scattered through multiple repositories: swift-docc swift-docc-render swift-docc-symbolkit Apple hosts documentation about DocC (presumably writtenContinue reading “Adding DocC to an existing swift package”
Creating Machine Learning Models with CreateML
I have been following the bare outlines of building, and using, machine learning models in Apple’s software ecosystem for a while. Most of my learning and personal research has been with foundational technologies – following some of the frameworks (TensorFlow, PyTorch, SciKit-Learn) and some of the advances in models and their results. Until this holiday,Continue reading “Creating Machine Learning Models with CreateML”
Apple’s M1 Chip Changes… Lots of Things
The new Apple Macs with an M1 chip in them is finishing a job that started a few years ago: changing my assumption that commodity hardware would always win. Having worked in the technology/computing field for over 30 years, you’d think I know better by now not to make such a broad assumption, even internally.Continue reading “Apple’s M1 Chip Changes… Lots of Things”
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”
post-WWDC – more device collaboration?
It’s been two weeks since WWDC as I’m writing this. I certainly haven’t caught all the content from this year’s event, or even fully processed what I have learned. I see several patterns evolving, hear and read the various rumors, and can’t help but wonder. Maybe it’s wishful thinking, or I’m reading tea leaves incorrectly,Continue reading “post-WWDC – more device collaboration?”
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”
Four strategies to use while developing SwiftUI components
Lets start out with the (possibly) obvious: when I code, I frequently make mistakes (and fix them); but while I am going through that process function builders are frequently kicking my butt. When you are are creating SwiftUI views, you use function builders intensely – and the compiler is often at a loss to explainContinue reading “Four strategies to use while developing SwiftUI components”
