Our DNA is written in Swift


Accessibility in SpeakerClock 1.3.1

You can now fully operate SpeakerClock with no or low vision. We gave SpeakerClock the full Accessibility treatment. In this article I describe some of the things I learned adding accessibility features to SpeakerClock, now that it is fully written in SwiftUI.

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. Amongst those my most successful one was iWoman, which I sold in 2015. My second-most-valuable (in terms of revenue) remained my beloved SpeakerClock, the last app standing.

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.

Adding Swift Package Manager Support – Part 1

As of Xcode 12, Apple has matured Swift Package Manger to a degree where it makes sense to add support for Swift packages to your libraries. There are still a few stumbling stones on the path which have no obvious solution. So I figure, I’d share with you how I got around them when I recently added SPM support to DTCoreText, DTFoundation and Kvitto.
