Technically Accessible, Actually Usable — A11y for 1M MAU in practise
[ Albert Wolszon · Senior Flutter Developer @ LeanCode ]
[ Artur Wiśniewski · Flutter Developer @ LeanCode ]
Most Flutter developers have touched the Semantics widget at some point - usually to set a label on a custom button, or to mute a decorative image. The moment you hand your app to a real screen reader user, the gap between technically accessible and actually usable becomes clear: everything is read, nothing is broken, and yet some flows are, in practice, painful to get through.
This is ~1 year a11y work on prod banking app - the kind of app where a visually impaired user has to move money, confirm a transfer, and recover from a validation error with confidence.
We'll show the perspective of the people we’re actually building for: we’ve spoken with long-time screen reader users how they really use mobile apps, and we’ll bring their conclusions into the room - what is okay and what is a painpoint.
We'll also show a set of concrete production cases - form errors and focus, reading order, status announcements, and a few more - each tied to the WCAG rule.

Building Server-Driven UI with Swift
[ Jonathan Bereyziat ]
How can you change an app’s UI without shipping a new version—and still keep the codebase modular, testable, and maintainable? This hands-on talk explores how to build a Server-Driven UI architecture with Swift, from the basic building blocks to a fully cross-platform approach.
We’ll look at how to model UI as data, build a modular component system, and turn server responses into native Swift interfaces. Along the way, we’ll explore how this approach can make A/B testing and experimentation much easier, how to safely roll out UI changes without an App Store update, and the quirks and limitations you need to consider to stay compliant with Apple’s App Store guidelines.
The talk will also cover how to structure a server-driven system that can power the same product across multiple platforms and devices, while still keeping the UI feeling native to each platform.
