If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method.

Troubleshooting

I've setup Phone Sign In in my FF project, but when testing on IOS, the SMS code aren't sent. Error says: "If app delegate swizzling is disabled, remote notifications received by UIApplicationDelegate need to be forwarded to FIRAuth's canHandleNotificaton: method."

Can anyone help me with this question?

What have you tried so far?

Some solutions on the internet says to downgrade "firebase_messaging" and "firebase_auth" or change "AppDelegate", but it's not possible with FF.

Did you check FlutterFlow's Documentation for this topic?

Yes
