Mohammad Azam presented on server driven UI in iOS. Server driven UI is an architecture pattern where the UI of a mobile app can be updated remotely by making requests to an API server. This allows changing the UI without requiring an app store update. Azam demonstrated how components like list views and rating views can be rendered dynamically based on responses from an API. He discussed lessons like maintaining compatibility with different app versions and requiring collaboration between mobile and backend teams. Source code and resources for learning more about this approach were provided.
