SwiftUI + Firebase template project

This is a template project with SwiftUI and Firebase. You can create an iOS with SwiftUI and Firebase right away without spending time on backend development! 🚀

Integrated Firebase services are following

  • Firestore Database
  • Firebase App Check
  • Authentication
  • Functions
  • Analytics


This app has the following design.

├── Animations                      # Lotties JSON files
├── Localization                    # Localization files (`*.strings`)
├── Utils                           # Utility functions 
├── Services                        # Service classes (business domain)
├── Repositories                    # Repository classes (data layer)
├── Views                           # View classes (view layer)
├── Extensions                      # Swift extension files
├── GoogleService-Info.plist        # Firebase config file (git ignored)
└── README.md
  • This project sets up necessary service classes in ContentView.swift through environmentObject. View files that need to access services simply declare @EnvironmentObject, like @EnvironmentObject var postService: SamplePostService.
  • Views/Styles.swift has a convenient view modifier called .style(_). You can style Text like Text("Hello world!").style(.header).
  • This project employs Lottie for rendering animations. Please refer Views/Common/LottieView.swift.
  • This project has integrated Firebase Authentication by default. You don’t have to force users to explicitly sign up for using your app.
  • This project has integrated Firebase Firestore. The UI of this project reflects the CRUD in real time. It is recommended to update the Firestore rules (see a following sample).
  • This project has integrated Firebase Analytics. Please refer Utils/AnalyticsUtil.swift. If you call AnalyticsUtil.logEvent(.something), this event will be recorded in Firebase Analytics.

Here is a sample of Firestore rule managed on Firebase Console. In this sample, posts has a user directory where only the owner can access. On the other hand, the second something is accessible for every logged-in users (anonymous login is fine).

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /posts/{userId}/{document=**} {
      allow read, update, delete: if request.auth != null && request.auth.uid == userId;
      allow create: if request.auth != null;
    match /something/{document=**} {
      allow read: if request.auth != null;

How to use

Just fork the repository on GitHub and go to “Create a new repository” page. You will find swiftui-firebase-template in the Repository template section! 😄

Then you have to set up a Firebase project.

  1. Clone your new repository to your local machine
  2. Create a new Firebase project (Please enable Firebase Auth anonymous login and Firestore)
  3. Add GoogleService-Info.plist in the new repository
  4. Start adding your own implementation

If you see build errors, you may need to remove and re-add Swift Package dependencies.


If you want to add some logic around database (Firestore), please refer to this documentation
