Convenience methods to manage Firebase Authentication in Swift projects.
- âś… Sign In With Apple
- âś… Sign In With Google
- âś… Sign In With Phone
Task {
do {
let (userAuthInfo, isNewUser) = try await authManager.signInApple()
// User is signed in
if isNewUser {
// New user -> Create user profile in Firestore
} else {
// Existing user -> sign in
}
} catch {
// User auth failed

import SwiftfulFirebaseAuthlet authManager = AuthManager(configuration: .firebase)
// Use Mock configuration to avoid running Firebase while developing (ex. for SwiftUI Previews).
let authManager = AuthManager(configuration: .mock(.signInAndOut))
// Use Mock configurations to override settings for Previews.
// .signInAndOut (default behavior)
// .signedIn (starts signed in)
// .signedOut (user starts signed out)

}- This SDK does NOT format phone numbers or provide UI for this. You must provide a string in the correct format.
- Phone numbers have to be correctly formatted, such as "+1 650-555-3434" for US numbers.
- See Firebase Docs for details about phone number implementation
- Possible resources for phone number formatting:
