海外TECH	DEV Community	Integrate Firebase Authentication with Google Sign-In to SwiftUI app	https://dev.to/kfurjan/integrate-firebase-authentication-with-google-sign-in-to-swiftui-app-1g4i	Integrate Firebase Authentication with Google Sign In to SwiftUI appSwiftUI framework is already in its third iteration and with that it is well and truly on its way to production ready applications Such applications are certainly going to need some sort of authentication Since authenticating users can be tricky you may want to rely on third party solutions for that such as Firebase Question is then how does one integrate Firebase and Google Sign In to SwiftUI application This article will show you how to create iOS application using SwiftUI create Firebase project and then use Firebase Authentication to integrate Google Sign In SDK to your SwiftUI application Within this article we will cover following topics Creation of Firebase projectCreation of SwiftUI Lifecycle applicationHandling dependencies with CocoaPodsHandling authentication within our codeDesigning UI elements Creation of Firebase projectIn order to use Firebase in our SwiftUI app we need to create new Firebase project in Firebase console Create new project by clicking on Add project Once Create a project page opens enter project name Next step is either enabling or disabling Google Analytics It is not necessary for this demo so it s up to you to enable it When project s Dashboard opens click on iOS icon Next fill out form for registering the app Apple Bundle ID is important since it needs to be the same as bundle identifier we will use later in Xcode project Other two fields are optional App Store ID is only needed if app will be uploaded to the App Store which we are not doing in this tutorial Click on Register app Next we need to download GoogleService Info plist file which will be added to Xcode project later In steps and just click Next since we will cover them in more detail later in the tutorial To finish registering the app click Continue to console Almost finished with setting up Firebase project Lastly we need to enable Authentication Click on Authentication and then on Get started Now choose Google as Sign in method provider Finally enable it by toggling Enable button add Project public facing name and Project support email Save this changes by clicking on Save button We are done with Firebase settings and now we are moving to actual coding Creation of SwiftUI Lifecycle applicationNext step is to actually create Xcode project Open Xcode select option Create a new Xcode project Once new window opens make sure that iOS is selected in header and then select App Click Next Now we need enter some details about project Product Name demoOrganization Identifier com firebaseInterface SwiftUILanguage SwiftCore Data and Tests are not needed for this tutorial so it is up to you to include them into the project Click Next and then choose folder where you want to save Xcode project Great We are ready for next section handling dependencies with CocoaPods Handling dependencies with CocoaPodsCocoaPods is a dependency manager for Swift and Objective C Cocoa projects It has over thousand libraries and is used in over million apps CocoaPods can help you scale your projects elegantly To handle project dependencies this tutorial will use CocoaPods If CocoaPods is not installed on your development machine follow this Getting Started guide on official CocoaPods page Using Terminal navigate to your project Use command similar to this one cd your project path Once in your project path initialize empty pod file by executing pod init command Open newly created Podfile to add dependencies needed for this project Add following content target swiftui do Comment the next line if you don t want to use dynamic frameworks use frameworks Pods for swiftui pod Firebase Core pod Firebase Auth pod GoogleSignIn endTo install these dependencies execute pod install command Awesome Project setup is done and its dependencies are successfully installed Handling authentication within our codeFirst step is to take GoogleService Info plist file we downloaded it in Creation of Firebase project section and drag amp drop it into Xcode project Once file is added to the project we need to add REVERSED CLIENT ID key to project configuration Handling REVERSED CLIENT ID keyDo the following Open your project configuration double click the project name in the left tree view Select your app from the TARGETS section then select the Info tab and expand the URL Types section Click the button and add a URL scheme for your reversed client ID To find this value open the GoogleService Info plist configuration file and look for the REVERSED CLIENT ID key Copy the value of that key and paste it into the URL Schemes box on the configuration page Leave the other fields blank When completed your config should look something similar to the following but with your application specific values Now we can move on to some coding Adding AppDelegateSince iOS and SwiftUI Apple added ability to include AppDelegate to SwiftUI Lifecycle app which we will need to add to our project Right click on project in Xcode left tree view and then select New file Add new Swift file named AppDelegate Once create add following contents to the file import Firebaseimport GoogleSignInclass AppDelegate NSObject UIApplicationDelegate func application application UIApplication didFinishLaunchingWithOptions launchOptions UIApplication LaunchOptionsKey Any nil gt Bool FirebaseApp configure return true func application app UIApplication open url URL options UIApplication OpenURLOptionsKey Any gt Bool return GIDSignIn sharedInstance handle url Adding helper functionsFor signInWithConfiguration presentingViewController callback method we will use later we need to provide presenting ViewController and GIDConfiguration configuration thus we need to implement two helper functions GIDConfigurationExtensions swift import Firebaseimport GoogleSignInextension GIDConfiguration Get GIDConfiguration instance by providing clientID from GoogleService Info plist file Returns GIDConfiguration instance static func getGIDConfigurationInstance gt GIDConfiguration GIDConfiguration clientID FirebaseApp app options clientID UIApplicationExtensions swiftimport UIKitextension UIApplication Get root UIViewController of application If for whatever reason UIViewController can not be accessed invoke fatalError since UIViewController instance is crucial for application for work properly Returns root UIViewController static func getRootViewController throws gt UIViewController let scenes UIApplication shared connectedScenes let windowScene scenes first as UIWindowScene let window windowScene windows first guard let uiViewController window rootViewController else fatalError return uiViewController With this finished we can move start implementing ViewModel Implementing LoginViewModelCreate new Swift file named LoginViewModel LoginViewModel import Firebaseimport GoogleSignInfinal class LoginViewModel ObservableObject Published var isUserLoggedIn false func signIn do let config GIDConfiguration getGIDConfigurationInstance let uiViewController try UIApplication getRootViewController GIDSignIn sharedInstance signIn with config presenting uiViewController user error in guard error nil else return guard user nil else return self isUserLoggedIn true catch print error localizedDescription func signOut GIDSignIn sharedInstance signOut isUserLoggedIn false Designing UI elementsNow comes last piece of the puzzle Designing UI elements using SwiftUI framework and connecting UI with business logic we implemented earlier LoginViewCreate new SwiftUI View file named LoginView LoginView import SwiftUIstruct LoginView View EnvironmentObject var viewModel LoginViewModel var body some View VStack Spacer Button action withAnimation viewModel signIn HStack Text Sign in with google fontWeight bold foregroundColor white padding frame maxWidth infinity background black cornerRadius padding Spacer struct LoginView Previews PreviewProvider static var previews some View LoginView LoginView will look something like this HomeViewCreate new SwiftUI View file named HomeView HomeView import GoogleSignInimport

this Connecting all togetherAll that is left to do is to connect it all together in DemoApp and ContentView DemoApp import SwiftUI mainstruct DemoApp App UIApplicationDelegateAdaptor AppDelegate self var appDelegate StateObject var viewModel LoginViewModel var body some Scene WindowGroup ContentView environmentObject viewModel ContentView import SwiftUIstruct ContentView View EnvironmentObject var viewModel LoginViewModel var body some View if viewModel isUserLoggedIn HomeView else LoginView struct ContentView Previews PreviewProvider static var previews some View ContentView This is it Integration of Firebase Authentication with Google Sign In to SwiftUI application is done and our project is ready to be run on emulator or physical device ConclusionThank you for reading and and I hope this article was useful for you since integrating Firebase Authentication with SwiftUI Lifecycle application is not exactly straightforward If you like my content and find it useful please
