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:

I think this is the correct solution:

1. pod repo update
2. pod update

But I had the same issue and solved it doing the following steps on the command line:

1. pod repo update
2. Commented the pod 'Firebase' line from my Podfile
3. pod install (this removed the old Firebase)
4. Added the pod 'Firebase' line again.
5. pod install (added the new Firebase)

2nd and 3rd steps were the key I think, otherwise CocoaPods didn't try to update it. As I said maybe this could've been solved by doing pod update but now I can't go back and try again.

After all of this you should see something like: Installing Firebase (3.2.0) Installing FirebaseAnalytics (3.2.0) Installing FirebaseInstanceID (1.0.6) Installing GoogleInterchangeUtilities (1.2.1) Installing GoogleSymbolUtilities (1.1.1) Installing GoogleUtilities (1.3.1)
