To build a website, we used PHP. To build a mobile application, we used something else. It was a simple rule. Almost self-evident.

Then one day, a request arrived, the kind every team eventually hears: "The website is great. Now we need a mobile app." From there the script is usually familiar: new technologies, new skills, new hires, new lines in a README nobody will read.

In this talk, I'll show how Symfony UX Native quietly bends what we thought was an immovable line between web and mobile. Through concrete demos, we'll see how a single Symfony codebase (Twig templates, Doctrine entities, Form types, all of it) turns into a real iOS and Android application via Hotwire Native. We'll write a bridge component live. We'll watch ux_is_native() reshape a single template for two surfaces. We'll talk honestly about architecture, developer experience, the limits of the approach, the use cases where it genuinely shines, and the questions every PHP developer asks the first time they see it work.

Because in the end, the surprising thing isn't that a mobile application can be built with Symfony. The surprising thing is that it's starting to feel perfectly logical, even though PHP wasn't supposed to do that.

(PS: No PHP developer was harmed, or forced to learn Swift, during the preparation of this talk.)
