Guideline 4.0 - Design
We noticed that the user is taken to Safari to sign in or register for an account, which provides a poor user experience.
Next Steps
To resolve this issue, please revise your app to enable users to sign in or register for an account in the app.
We recommend implementing the Safari View Controller API to display web content within your app. The Safari View Controller allows the display of a URL and inspection of the certificate from an embedded browser in an app so that customers can verify the webpage URL and SSL certificate to confirm they are entering their sign in credentials into a legitimate page.
