Big red LED digits allow you to see the timer even at great distance so you are free to move while you give the talk of your life. SpeakerClock emulates the famous countdown clock that all speakers at TED conferences need to adhere to.

The latest version is a universal app with HD-support for iPad, multiple presets and lots of usability enhancements. New portrait support allows you to put your iPhone/iPad in the cradle and still use SpeakerClock. Now the whole screen flashes if you transition into a new phase of your speech.

Swift Cross Platform

My passion for cross platform software development started around the year 2000 when I saw how a contractor at Austria’s Connect Austria – which eventually became the cellular network provider DREI – would create C++ utilities on PC with Visual Studio that then could be compiled and run in production on Compaq Tru64 Unix. I have fond memories of writing a lot of small CLI utilities the same way to solve data issues we encountered processing call record data for billing.

I always hated the approach of emulating a virtual machine to get code running of different platforms. This feels to me like watching the trojans celebrate their big wooden horse and nobody willing to listen to me shouting warnings of what ugliness might be inside.

Agentic Bash

The components I’ve been announcing recently certainly hinted at what I’m working on at the moment. A bash playground that lets me exercise SwiftBash, SwiftScript and SwiftPorts all tied together via ShellKit. There was one part that was on my private repo: the agentic harness and pure Swift wrappers for OpenAI APIs. I kept thinking that if I wanted to eventually make my Bash Playground public, then I needed to also have this final part on GitHub as well.

My Outer Loop

There is a thing that happens, after a couple of weeks of working with coding agents at a steady pace, where you stop thinking of yourself as the person typing and start thinking of yourself as the person seeing. The Latin word for vision is visio, “I see”; the Italian visione and English vision both keep that. It’s a much older idea than the modern “mission statement on a slide” usage. It means: I have, in my head, a picture of where this should go.

Who is Cocoanetics?

The word Cocoanetics comes from the words Cocoa (the framework we use to program iOS apps) and Genetics (to build, make up). It simply states that we have living and breathing iOS development a level even deeper than “in your blood”.

Our apps and parts are often experiments, mostly pieces of art, but always carefully handcrafted. We’re still learning and getting better at coding every day. You benefit from this because our code gets better all the time and we share what we learn on our blog.
