Our DNA is written in Swift


Bug: “Testfield in Row of List with Movable Items”

I was trying to recreate an existing user interface view in SwiftUI but got stumped for a while by some erratic behavior. I’ve built a nice sample app which is also on GitHub. This has been filed as FB9715757.

SpeakerClock 1.3.0

I’ve been busy since I completely rewrote SpeakerClock in SwiftUI. That was version 1.2.0.

The App Store provides a concept called Universal Purchase, which is where purchasing an app on one device also unlocks it on all other supported platforms. In the previous version I added a Mac version. This update now adds the AppleTV version. Still a minor update, because the functionality is identical, yet all three versions benefit from improvements.

Rewriting SpeakerClock in SwiftUI

When I started out developing iOS apps, 11 years ago I put several apps on the App Store. Since they became fewer and fewer as the income from them didn’t warrant updating them.

Some Statistics for Starters

As a hobby, I am working on a SwiftUI app on the side. It allows me to keep track of height and weight of my daughters and plot them on charts that allow me to see how “normal” my offspring are developing.

I’ve shied away from statistics at university, so it took me so time to research a few things to solve an issue I was having. Let me share how I worked towards a solution to this statistical problem. May you find it as instructive as I did.

Note: If you find any error of thought or fact in this article, please let me know on Twitter, so that I can understand what caused it.

Adding Swift Package Manager Support – Part 2

In the previous post I looked at some of the history of how we packaged up our library code for use by our fellow developers. We looked at some of the benefits of static libraries versus dynamic frameworks which also come with headers needed by the integrator.

Now let’s dive into the steps that were necessary for me to enable SPM support on the first few libraries DTCoreText, DTFoundation and Kvitto. It took me several days to iron out all the kinks and I’d love to share with you what I learned in the process.
