React Native is now available on iOS as of React Native 0.64 - the latest version of the React Native comes with support for the Hermes engine on iOS. Hermes on iOS made the app start ~40% faster than JSC. The difference is least significant on the latest iPhone 12 family that is powered by A14 Bionic. The TTI improvements alone are remarkable – your users will definitely enjoy your application launching in a blink of eye! The latest release of ReactNative is something I highly recommend.
