We run a small delivery service and need an iOS app that automatically plans the most efficient multi-stop route using live traffic. Drivers should see an ordered, fast-scrolling list of stops where they can quickly mark progress (arrived, delivered, skipped). When the route is re-optimized or dispatch inserts a new priority stop, the list must refresh instantly and keep the UI responsive. Stops come from our backend, and the app should be able to replan in real time as conditions change. Please build this with a SwiftUI interface and keep a clear MVC separation of concerns. Prioritize smooth performance and low-latency updates.
