# Firebase & Combine Sample This sample demonstrates how to use Firebase's Combine APIs. ## How to use ### Set up a Firebase project 1. Create a new Firebase project via the [Firebase console](https://console.firebase.google.com/) 2. Enable the required Firebase services in the Firebase project you created in step 1 * Firebase Authentication * Enable Anonymous Auth 3. Register this demo app as an iOS project 4. Download `GoogleServices-Info.plist` and drag it into your project (it's easiest if you place it just next to `Info.plist`) ### Enable Combine Currently, Combine support for Firebase is still under development, which is why we haven't enabled the respective Swift Package Manager products yet. You need to do so yourself: In `Package.swift`, find the following lines: ```swift // TODO: Re-enable after API review passes. // .library( // name: "FirebaseCombineSwift-Beta", // targets: ["FirebaseCombineSwift"] // ), // .library( // name: "FirebaseAuthCombineSwift-Beta", // targets: ["FirebaseAuthCombineSwift"] // ), // .library( // name: "FirebaseFunctionsCombineSwift-Beta", // targets: ["FirebaseFunctionsCombineSwift"] // ), // .library( // name: "FirebaseStorageCombineSwift-Beta", // targets: ["FirebaseStorageCombineSwift"] // ), ``` and uncomment them: ```swift // TODO: Re-enable after API review passes. .library( name: "FirebaseCombineSwift-Beta", targets: ["FirebaseCombineSwift"] ), .library( name: "FirebaseAuthCombineSwift-Beta", targets: ["FirebaseAuthCombineSwift"] ), .library( name: "FirebaseFunctionsCombineSwift-Beta", targets: ["FirebaseFunctionsCombineSwift"] ), .library( name: "FirebaseStorageCombineSwift-Beta", targets: ["FirebaseStorageCombineSwift"] ), ``` The app should now compile.
