(1) Context: Our project has a login feature via WEBVIEW (using SFSafariViewController) and integrates PassKey on the Web side.

The app listens for a successful login by capturing the redirect URL via the delegate of SFSafariViewController.

(2) Issue:

On iOS < 18.4: The redirect URL is captured with full parameters returned.

https://xyz.com/home?session_state=...&code=...

On iOS ≥ 18.4: The redirect URL is captured successfully but missing parameters.

https://xyz.com/home

We currently suspect that the issue originates from the SFSafariViewController framework after the release of iOS 18.4.

Has anyone experienced a similar issue? We would also appreciate support from the Apple team.

Thank you for sharing your post. Could you provide a simple sample or recording demonstrating that the code does not function correctly on iOS 18.4, while it was previously working and passing the parameter prior to iOS 18.3?

Have you attempted a test by adding the link with parameters using Notes, tapping and holding to open the app with the parameters, and verifying if it still works on iOS 18.4?

Would you be willing to open a bug report for this issue?

Once you open the bug report, please post the FB number here for my reference.
