Shopify is moving from React Native back to Swift and Kotlin
Source: Hacker News ↗
Shopify announced that it will transition its major mobile applications—from the Shopify, Shop, Point of Sale, and Inbox apps—to native development using Swift for iOS and Kotlin for Android, reversing the 2020 decision to adopt React Native. The shift is driven by advances in large language models (LLMs) that now handle much of the implementation, translation, testing, and review work previously required to maintain two separate codebases, diminishing the cost advantage that React Native once offered. By late 2025, Shopify’s AI‑assisted workflow proved capable of rebuilding core components in native languages quickly, prompting a reassessment of the mobile stack from first principles and leading to a greenfield migration strategy, beginning with the Shop app, which was rebuilt and released in app stores within 12 weeks.
The primary consequence of this change is that the benefits of shared implementation across platforms have been eroded, while native development retains advantages such as closer alignment with platform capabilities, first‑party tooling, and fewer dependency layers. Shopify’s experience shows that, although native development still requires maintaining two separate codebases, LLM agents now reduce the effort enough to make the trade‑off favorable. The company also highlighted that React Native apps remain fast and that it will continue to support critical open‑source libraries it created, such as FlashList, which sees roughly two million weekly downloads and will be maintained through discussions with potential new stewards. A smaller library, Restyle, will be archived but kept functional until the end of 2026, with an invitation for the community to fork and maintain it.
To ensure a smooth transition, Shopify built a system called Helix that orchestrates incremental migration by breaking down the React Native code into small, reviewable checkpoints. Each checkpoint must pass automated tests, visual verification, and adversarial code reviews before proceeding, preventing the creation of unmaintainable one‑shot translations. The greenfield approach, exemplified by the rapid Shop app rebuild, demonstrates how AI‑driven development can accelerate native migration without halting feature delivery. Millions of merchants and buyers who rely on Shopify’s suite of apps will see continued updates, while the broader developer community benefits from the continued maintenance of key React Native libraries and the open invitation for new stewardship of FlashList.
