User Authentication with Face ID/Touch ID in SwiftUI

Authentication is important to keep your user’s information safe but asking for a username and password every time they land on your app can spoil the experience. Face ID or Touch ID (AKA. Biometric Authentication) provides a convenient way to authenticate users without the need to enter a username and password.

Your app users can rely on biometric authentication like Face ID or Touch ID to enable secure, effortless access to the app. As a fallback option, and for devices without biometry, passcode or password serves a similar purpose.
