React Native was announced by Facebook in 2015 with a promise that rewrote the calculus of mobile development: learn once, write anywhere. The promise was qualified from the start — React Native was never write once, run anywhere in the way that early web-based mobile frameworks had claimed to be — but it was credible enough to reshape how a generation of mobile teams made technology decisions.

Eleven years later, React Native is used in production by Microsoft, Shopify, Coinbase, and thousands of smaller organizations. It has survived the emergence of Flutter, the maturation of Kotlin Multiplatform, and a period of internal uncertainty at Meta when the framework’s future was genuinely in question. Its survival reflects something real about the problem it solves and the ecosystem it has built.

The question of whether to build natively for iOS and Android or to abstract across both platforms with a cross-platform framework has occupied mobile development teams for more than a decade. The answer has not settled. What has settled is the character of native development itself — and in 2026, Swift and Kotlin have each reached a maturity that makes the native argument significantly stronger than it was five years ago.
