Shopify says 30 engineers rebuilt its mobile app from React Native into Swift and Kotlin in 12 weeks, with agents writing most of the code. The migration covered more than 300 screens, and users stayed logged in with their preferences preserved.

The company reports median launch times fell from 1.71s to 0.87s on Android and from 0.70s to 0.60s on iOS. Android crash-free sessions increased from 99.66% to 99.98%. Shared architecture and checks let agents test much of the app without a simulator, while humans still review every pull request. Shopify says the workflow moved bottlenecks into compute, review, merging and coordination.
