I haven't done this in a project myself. How do you get an instance of Auth other than calling Auth.auth() ? Do you have a sample implementation on how you'd initialize this?

You can start off with configuring a FirebaseApp with custom options.
FirebaseApp.configure(name: appName, options: options)

Then you can access the FirebaseApp by name
let firebaseApp = FirebaseApp.app(name: appName)

Then you can instanciate an Auth instance with FirebaseApp
let firebaseAuth = Auth.auth(app: firebaseApp)

Same thing can be done with Firestore and Storage
let firebaseFirestore = Firestore.firestore(app: firebaseApp)
firebaseStorage = Storage.storage(app: firebaseApp)


func getAuthenticatedUser() -> UserAuthInfo? {
if let currentUser = Auth.auth().currentUser {
if let currentUser = auth.currentUser {
return UserAuthInfo(user: currentUser)
} else {
return nil
