# SwiftUI component inside a React Native View inside a Host does not render

> A React Native view inside a Host switches back to React Native layout, so SwiftUI below it needs its own Host.

Expo. Likely fix, 4 October 2026.

Versions: Expo SDK 57, @expo/ui

There is no error message for this one, only the symptom in the title.

## Cause

A React Native view inside a Host switches back to React Native layout, so SwiftUI below it needs its own Host.

## Fix

Wrap the nested SwiftUI component in another `<Host>`, or keep SwiftUI controls and RN layout in separate blocks (`RNHostView` for RN inside SwiftUI).
