Firebase Database Quickstart

This Firebase quickstart showcases how Firebase Realtime Database (RTDB) can store and sync data. Data is synced across all clients in realtime, and remains available when the app goes offline. You can read more about Firebase Realtime Database here!

To view the SwiftUI quickstart, view the DatabaseExampleSwiftUI/DatabaseExample directory.

Getting Started

Clone and open Database quickstart project

  • Clone the quickstart repo and cd into the database/DatabaseExampleSwiftUI/DatabaseExample directory.
  • Open file DatabaseExample.xcodeproj project using Xcode.
$ git clone
$ cd database/DatabaseExampleSwiftUI/DatabaseExample
$ open DatabaseExample.xcodeproj
  • Once the .xcodeproj is opened, update to the latest Swift Package Versions: go to the menu bar, click on File > Swift Packages > Update to Latest Package Versions

Connecting to the Firebase Console

  • To have a functional application, you will need to connect the Database quickstart example with the Firebase Console.
  • For an in-depth explanation, you can read more about adding Firebase to your iOS Project. Below is a summary of the main steps:
    1. Visit the Firebase Console
    2. Add an iOS app to the project. Make sure the Bundle Identifier you set for this iOS App matches that of the one in this quickstart.
    3. Download the GoogleService-Info.plist when prompted.
    4. Drag the downloaded GoogleService-Info.plist into the opened quickstart app under the Shared folder.
  • Create a Database and update the rules to database rules.
  • Now you should be able to build and run the Firebase project!

When using earlier versions of xcode (12.5 or below) there is a bug where SwiftUI toolbar disappears after navigation on tvOS. This issue is resolved when using the latest version of xcode (13.5 or above).
