You can open each of the following samples as an Xcode project, and run them on a mobile device or a simulator. Simply install the pods and open the .xcworkspace file to see the project in Xcode.
$ pod install --repo-update $ open your-project.xcworkspace
When doing so you need to add each sample app you wish to try to a Firebase project on the Firebase console. You can add multiple sample apps to the same Firebase project. There's no need to create separate projects for each app.
To add a sample app to a Firebase project, use the bundleID from the Xcode project.
Download the generated
GoogleService-Info.plist file, and copy it to the root
directory of the sample you wish to run.
