Firebase Demo Code with Swift5

 Firebase Demo Project

The Firebase Realtime Database lets you build rich, collaborative applications by allowing secure access to the database directly from client-side code. Data is persisted locally, and even while offline, realtime events continue to fire, giving the end user a responsive experience.

Firebase Authentication aims to make building secure authentication systems easy, while improving the sign-in and onboarding experience for end users. It provides an end-to-end identity solution, supporting email and password accounts, phone auth, and Google, Twitter, Facebook, and GitHub login, and more.

Demo Code

1. Create a project with an iOS app using the Firebase Console, and connect your iOS app to the newly created Firebase project with the use of GoogleService-Info.plist, which is a file generated during your app registration and containing important information, e.g. PROJECT_ID , BUNDLE_ID and API_KEY .
2. Add the Firebase Authentication pod to your Podfile and run pod install afterward.
3. Initialise the Firebase configuration in AppDelegate.swift at the start of the app:
4. Enable Email/Password authentication in the Authentication section in the Firebase Console:

Code:-

let email = "example@gmail.com"
	let password = "testtest"
	Auth.auth().createUser(withEmail: email, password: password) { authResult, error in
	if let error = error as? NSError {
	switch AuthErrorCode(rawValue: error.code) {
	case .operationNotAllowed:
	// Error: The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section.
	case .emailAlreadyInUse:
	// Error: The email address is already in use by another account.
	case .invalidEmail:
	// Error: The email address is badly formatted.
	case .weakPassword:
	// Error: The password must be 6 characters long or more.
	default:
	print("Error: \(error.localizedDescription)")
	}
	} else {
	print("User signs up successfully")
	let newUserInfo = Auth.auth().currentUser
	let email = newUserInfo?.email
	}
	}
