Migrating to Expo SDK 54 involves following detailed checklists and step-by-step guides to handle breaking changes like Hermes enforcement and API updates while upgrading React Native 0.81 and React 19.1.

React Native 0.81 and Expo SDK 54 introduce precompiled XCFrameworks, React Compiler support, iOS Liquid Glass effects, and Android edge-to-edge display. These features enhance native performance and visual design capabilities across platforms.

Yes, Expo SDK 54 enforces the Hermes JavaScript engine as a breaking change from SDK 53. Developers must ensure their native modules and JavaScript dependencies are fully compatible with Hermes during the migration process.

Integrating TurboModules with the React Native New Architecture requires leveraging the updated native module integration guides. This process facilitates understanding of the new architecture to connect native iOS and Android code efficiently.

Yes, you can use the React Compiler with your existing Expo application by upgrading to SDK 54 and React 19.1. The compiler works automatically to optimize component rendering and reduce manual memoization overhead.

Precompiled XCFrameworks in Expo SDK 54 are prebuilt native iOS binaries that eliminate the need for local compilation during development. They significantly reduce iOS build times and simplify the native dependency management process.
