Alyona will tell you how the Sberbank Online platform team managed to reduce the local build time by 3 times using a customized approach and a pinch of Gradle magic.

We'll discuss how to make simple, feature-rich declarative-style navigation without routers and coordinators, relying on SwiftUI technology standards. The final solution will have iOS 14 support and NavigationStack capabilities, and it will be free of SDK flaws and bugs.

There is a 3D engine that works well on mobile devices, and there are native mobile applications. And it seems like you could combine them – like in the old Pen-Pineaple-Apple-Pen meme. But all this is not that obvious.

During the talk, the speaker will share his practical experience of implementation.

We'll look at how we can reduce the application size, as well as conclude that one of the most important aspects in this process is getting rid of localization strings and xcasset catalogs. The speaker will explain how this can be done with minimal costs and without large-scale refactoring of the entire application.

Local authentication is used to securely log into an application with sensitive data. The speaker will explain how it can be implemented on Flutter, why they do it and what are the advantages of such a solution.
