This post is from the WWDC26 Foundation Models Q&A.
React Native + native AI bridge
Recommended
There is no official React Native binding for the Foundation Models framework.
For Expo/React Native apps with committed ios/ projects, is a thin Swift native module wrapping Foundation Models the recommended pattern, or does App Review / platform policy expect FM usage only from fully native UI flows?
Are there memory, background, or entitlement constraints that make FM impractical when invoked from RN via a bridge (vs pure SwiftUI)?
