Learn how to implement multiple user interfaces for an application without requiring any of the user interfaces to implement functionality in this 43-minute conference talk from GDevCon N.A. 2025. Discover the advantages of this approach, including eliminating the need to write multiple application variants and the ability to customize user interfaces for different use cases with minimal or no changes to the core application. Explore an elegant, scalable, and reusable implementation that provides developers maximum flexibility in meeting changing interface requirements without impacting project schedules. Gain insights into user interface abstraction techniques that separate presentation logic from business logic, enabling more maintainable and adaptable software architecture.
