Framework
React Native is an open-source framework from Meta for building mobile apps using JavaScript and React, letting developers share code across iOS and Android.
iOS 27 kills apps built with the Xcode 27 SDK at launch unless they adopt the UIScene lifecycle, a dev.to post says. Xcode 26 builds still launch on iOS 27, so the toolchain upgrade is what creates the exposure.
Reality
React Native Skia v3 renders through Skia's Graphite backend on Dawn and raises the minimums to Android API 26 and iOS 15.1. Graphite does not run on tvOS, Android TV or Mac Catalyst, so apps that target them stay on the maintained v2 line.
Reality
Shopify is moving every mobile app off React Native to Swift and Kotlin, with its Shop app in stores 12 weeks after a one-week agent-built prototype. The shipped app came out of a gated, screen-by-screen review process that a team copying Shopify would have to build first.
Reality
Expo opened a three-to-four-week SDK 58 beta that moves apps onto iOS 27's required scene-based lifecycle and React Native 0.88 RC. Teams have that long to find launch and layout breakage in their own configurations before the release goes stable.
Reality
Shopify is moving every one of its apps off React Native to native Swift and Kotlin, and rebuilt its Shop app that way in 12 weeks. The switch leaves three Shopify-maintained React Native libraries, including the widely used FlashList, archived or without a maintainer.
Reality
Munchable's 10-pound Premium plan takes every displayed and charged price, in 24 currencies, from one package with zero runtime dependencies. With the rounding kept in that package, the web site and the Expo paywall print the amount Checkout charges.
Reality
Six engineers shipped a fully native Shop app in 12 weeks, but the first attempt at handing the React Native code to a model produced what Shopify's engineering director called slop. Helix chunks each screen instead.

Shopify's Helix ports its 300-plus-screen app off React Native in small LLM-built checkpoints, each held behind four gates. The design assumes the model's first attempt is wrong, so most of the adoption cost sits in test harnesses and a written architecture.
Reality
The beta runs three to four weeks with React Native 0.88 as a release candidate, and Expo says stable follows once 0.88 lands. Most of what teams have to test is iOS 27 behaviour: scene life cycle, resizable windows, orientation locks.
Reality
The sixth item in OWASP's mobile list is rated low technical impact and severe business impact. A dev.to walkthrough argues React Native stacks carry extra exposure, and the reason it gives is the telemetry that arrives with dependencies.
Reality
Shopify is dropping React Native five years after standardising on it, on Head of Mobile Mustafa Ali's estimate that two native codebases now beat a shared runtime. Its reported gains compare against React Native's old architecture.
Reality
React Compiler 1.0 checks each component against the Rules of React and leaves the failures unoptimized, so lint debt is now a performance question. The December Server Function advisories only reach apps that run a server.
Reality
Shopify's case for dropping React Native rests on agents porting features between iOS and Android. The tooling built around those agents shows how much human review that still takes, and what the switch costs in hotfix speed.
Reality
Shopify's five-year retrospective gives figures for speed and stability, describes the productivity gain in words alone, and says iOS and Android specialists remain essential to its apps. The mix limits how much of it an outside team can borrow.
Reality
Cyfamod moved two Expo apps off EAS and onto GitHub Actions, and found that both the upload keystore and the version counter lived outside the repository, where a fresh runner could see neither.
Reality
Salesforce's Sneha Singla describes one personalization architecture behind iOS, Android, React Native and Flutter, in which developers register the native components and the zones they may fill, and marketers choose the rest.
Reality
In SDK 57 the DSL that listed what a module exposed becomes annotations on ordinary Swift methods, and Swift's own mutability and async keyword now decide what JavaScript sees. Views and Android come later.
Reality
Software Mansion spent almost a year on Discord's iOS app after the New Architecture switch was already on, and its ticket breakdown puts build systems, codegen and dependency bumps at 14 percent of the work to reach parity.
Reality
A cron built to defeat Render's 15-minute spin-down spent the workspace's shared machine-hour budget in about ten days, and the suspension that followed took production and staging down together.
Reality
A suspended app takes the fetch promise with it and comes back with a fresh JS runtime, so the only durable parts of an upload are the row you wrote before it started and the server state you reconcile against.
