iOS - Firebase error: Use of unresolved identifier FIRApp running supplied code

Question

When trying to configure XCode to work with Firebase 3, using the code in the setup docs gives me an error:

https://firebase.google.com/docs/ios/setup#add_the_sdk

Answer 1

Solve this problem like this:

import FirebaseAnalytics

Then need to replace FIRApp with FirebaseApp as FIRApp is deprecated.

Thanks.
