Good morning, it's Friday, October 2nd, 2026, and this is NativeScript iOS Daily.
No broader pattern today, just one high-impact change. A runtime fix restores correct native dispatch when iOS objects are wrapped in a JavaScript proxy.
The context is modern framework reactivity. In pull request 485, the author shows that when a native object wrapper is wrapped in a proxy — which is what Vue 3 does to anything stored in component data with its reactive system — the runtime could no longer find the native object underneath. The results were severe…
The fix is to unwrap proxy receivers and arguments before dispatch to native code. In practical terms, the bridge now looks through the proxy to find the real object, across argument conversion, interop dispatch, and related helper logic. That breadth makes sense, because every path into native code needs the same…
Developer impact is reliability and compatibility. If you keep native views, controllers, or other iOS objects in reactive state, you should no longer see mysterious crashes or missing values. Proxies become transparent to the bridge, preserving normal JavaScript behavior while keeping native calls correct.
What's next is…
