React Native: Locking Down the C++ API

Most activity centers on tiering C++ headers into public, frameworks, and private with umbrella-only access under strict API mode. Paired with that are practical fixes for bridgeless split bundles, iOS library builds, and layout performance.

Hello, it's Monday, October 5th, 2026, and this is your React Native briefing.

The headline is a coordinated push to lock down the C++ public interface, alongside a few high-impact runtime and build fixes.

First, the API boundary work. About two-thirds of the activity, largely from one author, retires headers into private or frameworks tiers and requires app code to include through module umbrellas instead of direct includes. Evidence includes proposal 58837, which filters snapshots to public headers only, and…

Second, build reliability and log noise. Proposal 58845 fixes broken iOS nightly builds for libraries like clipboard, where missing coroutine headers caused a file-not-found error, by disabling folly coroutines in library pods. Related Android changes, like proposal 58854, demote the missing generated setter message…

Third, runtime correctness and performance. Commit 2 A 2 C C A A installs the global eval with source URL helper on bridgeless, fixing development split bundles loaded with lazy import that failed with parsing source unsupported. And proposal 58833 memoizes minimum content size in layout, fixing exponential…

What's next: if you ship native code, test with the…
