Description

When loading webauthentication screen on flutter, since iOS 18, the app shows a white blank page.

This has been reported also for the react-native auth0 package here

There's a workaround on the react-native by upgrading iOS sub-dependencies of Auth0 to 2.10.0

I've tried to do so with the provided auth0_flutter.podspec file but haven't been able to make it work.

This is currently blocking users to login/signup using auth0 for builds created with latest SDK.

Reproduction

1. Launch app with latest package on iOS 18.1 Simulator
2. Bring the webAuthentication view

I'm having the exact same issue. Blank page that never loads.

The page loads in android (though rather slow) and in my desktop browser (instantly) without errors.

I have seen this occur on simulators running iOS 18 and 18.1. Any simulated devices running iOS versions before 18 are fine (like 17.5).

I also tested on a real iPhone XS Max running iOS 18.1 and could see the appropriate login screen (not blank). This issue may be isolated to simulators.

Same issue, running on 18.X on a simulator, the login view fills the screen and freezes.

As mentioned here on the react-native project, there seems to be some suggestion to remove "EXCLUDED_ARCHS[sdk=iphonesimulator*]" = arm64;, which at least in the case of our project has plastered the issue.

Hi everyone,

Please make sure you do not have arm64 in the EXCLUDED_ARCHS build setting of your app.
Closing, as this is an iOS simulator issue.
