About This Article

Problem

React Native apps were slow to build on iOS because React Native core got compiled from source every time developers did a clean build. The Legacy Architecture code also made both iOS and Android binaries larger than they needed to be.

Solution

The React Native team made precompiled .xcframework binaries the default for iOS builds and added the RCT_REMOVE_LEGACY_ARCH flag to skip compiling Legacy Architecture code. This lets developers avoid recompiling React Native core and shrink their app size.

Impact

iOS builds are now much faster since React Native core doesn't get recompiled each time. App size went down because unused Legacy Architecture classes were removed from both platforms. This release included 650+ commits from 95 contributors.
