Shopify ditches React Native for Swift and Kotlin as coding agents change the build-cost math
mathemagic1an · x · 2026-09-11
Shopify announced it's moving mobile development from React Native back to native Swift and Kotlin. The 2020 bet on React Native paid off — one codebase, cross-stack contributors, no feature-parity chase — but coding models have improved so dramatically that building features natively no longer carries the old cost. When a core assumption behind the 2020 decision changed, the team re-evaluated the stack from first principles. Commenters draw the broader lesson: coding agents eliminate stack layers optimized for human consumption at perf cost — "the agent becomes the compiler," and someone may soon RL-train directly on machine code generation.
