Why use Firebase?

One of the best things about Firebase is that it allows real-time syncing of data. It also integrates well with a number of apps such as Google Ads and Slack to make the development process more efficient. Features such as Firebase Authentication makes the sign up/sign in process way much easier.

Firebase

After logging in, click on 'Add project' and name your project. Click on Continue, if you've Google Analytics, you can also add that to the project. Finally, click on 'Create project'. When it's done, click on Continue and you'll see the dashboard. Now, click on the settings icon and go to project settings.

Setting the App

In 'Your apps', select iOS. To get the iOS bundle ID, head over to XCode and then to Project Settings. Copy the Bundle Identifier and paste it as the input value of iOS bundle ID. Click on 'Register app' and then download the config file in the next step. Drag and drop the file in XCode, next to Lottie.

Install using SPM

To install Firebase using SPM, go to File → Swift Packages → Add Package Dependency... Enter the following URL. Select Firebase Auth at the end.

https://github.com/firebase/firebase-ios-sdk.git

Initialize Firebase

To initialize Firebase in our app, we'll need to import it first. At the top, add in an import statement as follows:

import Firebase

Then, before add an initializer that configures Firebase.

struct FirebaseLoginApp: App {
    init() {
        FirebaseApp.configure()
    }
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

Firebase Console Setup

Let's head back to the Firebase console and finish our setup. Since we're already done with steps 3 and 4, click 'Next' for both. The next step verifies the installation. For this, go to XCode and run the iOS simulator. After it finishes building the app, in the Console, you'll see a Congratulations message. This ensures the verification. Now, click on 'Continue to console' button.

Firebase Authentication

In this step, we'll start using Firebase authentication. In the sidebar, click on Authentication and then on the 'Set up sign-in method' button.

In Sign-in providers, select the Email/Password option and toggle the option that says 'Allow users...'. Click the 'Save' button.

Creating User

To create a user, click on 'Users' and then 'Add user'. Fill in the email as well as the password and then click on the 'Add user' button next to 'Cancel'.

Login Screen

Head back to Xcode in our login screen and Import Firebase.

import Firebase

Here, we'll add the following code inside the login function.

struct ContentView: View {
    @State var email = ""
    @State var password = ""

    var body: some View {
        VStack {
            TextField("Email", text: $email)
            SecureField("Password", text: $password)
            Button(action: { login() }) {
                Text("Sign in")
            }
        }
        .padding()
    }

    func login() {
        Auth.auth().signIn(withEmail: email, password: password) { (result, error) in
            if error != nil {
                print(error?.localizedDescription ?? "")
            } else {
                print("success")
            }
        }
    }
}

Testing

To test whether it works or not, you'll have to run the Simulator. You cannot test Firebase calls in the Preview. Once the simulator is running, you can enter the test email and test password we added via the Firebase Console.
