My Coding Journey
I have been coding for most of my life. My father taught me the first basics using Delphi (formerly Object Pascal) around 1997. I still remember my first „real“ project I created with my dad during a vacation in Sweden. It was a simple quiz that read the questions and possible answers from a text…

Distribute iOS apps “over the air”

Learn Accessibility on iOS With Me – Grouping and labels

Quick Tip: Running tests repeatedly in Xcode

Multiple Buttons in a SwiftUI List Element
If it looks like a button and behaves like a button, then it probably should be a button While writing another post for my accessibility series, I created a simple UI that contained a few Buttons inside of List row. A comparable example view could look like this: It’s just a list containing a single Element (the HStack), which itself…

A few weeks ago, a dear colleague of mine who attended the NSSpain recommended this talk by Daniel Devesa Derksen-Staats to me. In his talk, Daniel talks…
