alt Hacker News> I'm curious about the use cases people you know used Qt to develop for mobile.
They were developing non-trivial mobile apps. The kind where you use your fingers on a touch screen, but that are more complex than just showing a text and an image. Say Google Maps, or WhatsApp.
The problem was not the lack of components: the problem was that it was C++. C++ is more complex to write correctly than Swift or Kotlin and harder to debug. Which made those teams measurably a lot slower. It's just the wrong technology for the use-case, IMO.
I also write complex UIs with QML and C++. I do not consider myself an expert in C++ but there is clearly a subset of it that I feel comfortable in. I think the combo of QML & C++ is great since QML lets you focus on the UI - and does a great job at it, and in C++ you can write performant code. C++ isn't that complicated these days - if you stick to a subset you're familiar with.
