We implemented passkeys Autofill feature in iOS 16.6. Later verified in iOS 17.0 as well. But when we upgraded to iOS 17.5, the available passkeys autofill prompt is disappeared now. No code changes were done from our side. Also upgraded to iOS 17.5.1 and checked, still doesn’t show the prompt on the keyboard. For autofill we are calling 'performAutoFillAssistedRequests()' API on our ASAuthorizationController after fetching assertion options response from our Relying-Party. Our textFields content type is set to ‘username’. Additional Info: Before making the performAutoFillAssistedRequests() API call, when we click on the ‘Passwords’ icon on keyboard, it only shows the passwords saved on iPhone. But after making the call, we can see available passkeys as well in the list. We are making the fetch assertion options response call on textField delegate after typing more than two characters. I already raised a bug in Feedback Assistant on this - FB13809196. I attached a video and sysdiag file there.
