create firebase auth signin request in swift

Here's how you can create a Firebase Auth signin request in Swift:


main.swift
import Firebase

// Assume that you have already configured your Firebase app and imported Firebase module.

Auth.auth().signIn(withEmail: "example@gmail.com", password: "password") { authResult, error in
  if let error = error {
    // Error occurred while trying to sign in
    print("Failed to sign in with error: \(error.localizedDescription)")
  } else {
    // User successfully signed in
    print("User successfully signed in with email: \(authResult?.user.email ?? "")")
  }
}
486 chars
14 lines

Here, we are calling the signIn method on the Auth object and passing in the email and password as parameters. The signIn method performs the sign-in operation and when it is completed, it calls the closure where we can handle the result. If an error occurred while trying to sign in, we can access the error object and handle it appropriately. Otherwise, we can access the authResult object to get information about the signed-in user.
