fix(expo): forward inbound callback URLs to the native SDK on iOS by wobsoriano · Pull Request #9470 · clerk/javascript

wobsoriano · 2026-08-17T17:18:53Z

Description

Email link sign-in never completed on iOS. The native SDK finishes a magic link flow only from the callback URL, and the prebuilt AuthView picks that URL up via SwiftUI's .onOpenURL, which does not fire for the UIKit-hosted controller Expo mounts. The app reopened on the callback with the user still signed out and no error. Android is unaffected because clerk-android registers its own intent filter and catches the callback natively.

This adds an app delegate subscriber that forwards inbound URLs to the SDK. It returns false, so the URL stays available to React Native's Linking, and a URL arriving before JS calls configure is replayed once the SDK is ready.

Fixes #9450

📝 Walkthrough

Walkthrough

The Expo iOS module registers ClerkAppDelegateSubscriber to forward opened URLs to ClerkNativeBridge. The bridge queues callback URLs during configuration, replays the latest pending URL after successful configuration, and passes configured URLs to Clerk asynchronously. The podspec includes the Swift file, and a patch changeset documents the fix.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 578e3

This change forwards iOS callback URLs to the native SDK while preserving React Native URL handling; no actionable merge-blocking risk remains beyond normal checks and review.
