Swiggy

Swiggy's food delivery order process sequentially engages multiple subsystems including API communication, restaurant order acceptance system, rider dispatch algorithm, real-time location tracking, and status synchronization, each functioning independently in microservice form.

Real-time location tracking involves coordinated communication among multiple backend services such as the location service, order status service, and ETA calculation service, with results pushed back to the user interface via a push mechanism.

Swiggy is one of India's largest food delivery platforms.

When a user places an order, the app sends complete data including restaurant information, item details, delivery address, and payment information to Swiggy's backend system via API.

Before an order takes effect, the backend performs real-time inventory and item status checks on restaurant menu items, and intercepts the order if an item is sold out.

The rider dispatch system matches delivery riders by comprehensively considering the rider's current location, time, availability, and estimated time of arrival at the restaurant.

Platforms improve capacity utilization by using batch order logic to allow a single rider to complete multiple deliveries along a reasonable route.

Swiggy adopted a progressive migration strategy, focusing on high-impact user paths rather than a one-time complete rewrite.

After the native transformation, the app loads faster, scrolls more smoothly, and animations are more fluid, with the most noticeable differences on older devices.

Swiggy observed a significant increase in conversion rates and a noticeable decrease in bounce rates after nativization, with performance improvements directly translating into business results.

The Swiggy team initially attempted to fully replicate the existing UI in native, but later shifted to using native design patterns with minor adjustments, thereby improving component reusability and development speed.

During the migration, the team needed to balance execution speed with long-term architectural decisions, ultimately choosing to prioritize iterative delivery.

During the migration, it was necessary to ensure feature parity and establish clear ownership and coordination between the hybrid and native systems.

Swiggy migrated its Instamart and Dineout businesses from a hybrid architecture to a native app based on Swift and SwiftUI.

The Swiggy team started by rebuilding core pages with Swift and SwiftUI from the Instamart and Dineout home pages and search experiences, with the first batch of native experiences going live within weeks.
