It's almost time. Apps You Can Make Swift Coding Club premieres Sunday, September 20 at 00:00 UTC. For the US, that's tonight: 8:00 PM Eastern, Saturday, September 19 7:00 PM Central, Saturday, September 19 5:00 PM Pacific, Saturday, September 19 appsyoucanmake.com/club #SwiftCodingClub

iPhone screen showing a September 2026 calendar picker with Sunday the 20th selected in black, today the 19th ringed in light blue, and a time field reading 12:00 AM. Overlapping the bottom of the phone is the SwiftUI code that draws it: a DatePicker bound to a constant date in the UTC time zone, so it can't be changed.

Things are starting to come together for Apps You Can Make Swift Coding Club. Join us Sunday, September 20, 2026 #SwiftCodingClub appsyoucanmake.com/club

iPhone screen with three large overlapping circles: a red one at the top left reading "3 days until" in white, a yellow one at the right reading "Apps You Can Make" in black, and a green one at the bottom left reading "Swift Coding Club" in black. Beside and below them is the SwiftUI code that draws them — a ZStack holding three more ZStacks, each pairing a Circle with a Text and nudged into place with an offset.

Getting everything lined up for Apps You Can Make Swift Coding Club. HStacks, VStacks, and ZStacks are how we do that in SwiftUI. More on that starting Sunday, Sept 20. #SwiftCodingClub appsyoucanmake.com/club @appsyoucanmake.bsky.social

iPhone screen with a countdown built from colored blocks: a purple "4" beside a gray "days until"; green "Apps" beside blue "You"; red "Can" beside orange "Make"; and a wide yellow "Swift Coding Club" underneath. Below is the SwiftUI code that draws them — a VStack holding three HStacks and a final Text, each given padding and a background color.

iPhone screen with a countdown: "5 days until Apps You Can Make Swift Coding Club". Below it, the SwiftUI code that draws it: a ContentView whose body is four Text views, one per line.

I’ve been working on DiscOne because I missed the simple ritual of putting on an album and actually looking at the artwork while it plays. It is a music player that connects to Apple Music to bring back that CD collection experience. Here is a quick look at how it works. Launching on Tuesday.

Thinking about choosing a few CDs to listen to while playing Cribbage in the lounge at my college dorm. This is what led me to build my new app, DiscOne. I’m bringing back the intentional selection of albums. Make a choice and listen to the whole album. #ThrowbackThursday #iphone #music

Other people are only tall if they are significantly taller than me. Otherwise there are “roughly my height” people and then shorter people. But the my height people are rare enough that I do notice them.

Two years ago today, the Apple Vision Pro released and I have been using it nearly every day since. The visionOS platform keeps evolving and I’m excited to keep pushing the boundaries of spatial computing. In that time, I’ve been involved with shipping 5 public apps, and dozens of others. 🧵

Card game update. I have the logic for "super moves" in Freecell working perfectly with a tap or a drag and drop. I've been doing a significant refactor to the architecture of this app. Card game rules are declarative. My hope is this will let add more games in a rapid way after my initial launch.

Last night, I presented several apps I have in progress at STL Swift. Thanks to Charlie Chapman for organizing. My fellow presenters showed some great apps too: Dan Hart and Scott Gardner #STLSwift #SwiftUI #iOS #visionOS

Presentation of an iPhone game with colorful diagonal line background. The user moves a circular lens with a square hole around the screen, moving over the randomly scattered squares to collect them.

Presentation of a colorful Mac app, which allows for entry of letters for looking up matching words. Options available to match most popular word puzzle styles.

MeshInstancesComponent Stress Test in visionOS 26. Here I'm using MeshInstancesComponent with 160,000 instances to create a 4-iteration Menger Sponge / Sierpinski Cube. Since each cube is rather simple, I'm able to squeeze this many instances. in one RealityKit Entity.

Here’s a scene from my latest visionOS project. This has particle emitters from the space all around you, and from your hands, and has a mirroring representation of you. I’m using this as a stand in for another visionOS person to get a feel for how my scenes will feel to share them with others.

Preview of my latest open source for visionOS, macOS, and iOS: EntityView Why 1. Multiple overlapping RealityViews on visionOS aren’t really possible on iOS and macOS 2. Combining several clusters of Entities in the same RealityView doesn’t have a good pattern What would you want to add to this?

Since discovering that I can bring .STL files directly in to RealityView with ModelEntity, I’ve started using OpenSCAD for some of my layout thinking. This “programmer” style tool suits my thought process better for laying out and manipulating 3D elements. #visionOS #stl #openSCAD #RealityKit

Some days I am very productive with my hobby projects. Today was not one of those days. But, I did decide on what numbering system my aliens use. Can you figure it out?

Spreadsheet with numbers in the first column, and digits in the next columns. The digit columns have headers alternating 3 and 2.
One example is 53 with digits 1 1 1 1 1 1

I worked thru a lot of different interactions while building Cards Together this year. I’m really happy with where this landed: Tap to flip a card Drag to move a card (and any cards on “top” of it Drag around to gather cards, swipe into it to move the whole stack Drag into a stack to fan them out
