Then get the following error when trying to build the project... "No such module 'GoogleSignIn' SignInViewController.swift'

Try updating your version of CocoaPods and reinstalling. You have mixed major versions of Firebase in your codelab somehow, which can lead to other problems.

I had the same problem. I could fix it by rewriting the Podfile in folder ios-starter/swift-starter.
In particular I did:

1. Delete Podfile and Podfile.lock
2. In terminal in this folder, run pod init to create a Podfile.
3. Open the created Podfile and change it to:

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'FriendlyChatSwift' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for FriendlyChatSwift
  pod 'Firebase/AdMob'
  pod 'Firebase/Analytics'
  pod 'Firebase/Auth'
  pod 'Firebase/Database'
  pod 'Firebase/RemoteConfig'
  pod 'Firebase/Storage'
  pod 'Firebase/Crashlytics'
  pod 'GoogleSignIn'

end

4. Run pod install

Hope this helps.
