Firebase 3.x issue: FIRUserInfo is an "undeclared identifier"

No matter what I try, FIRUserInfo is an undeclared identifier. I'm trying to migrate from Firebase 2.x to 3.x: somehow the recent changes on google/firebase server side broke my app's facebook auth integration.

I made sure my Podfile installs FirebaseAuth 3.0.2. I made sure my header does import @FirebaseAuth. I tried cleaning my build folder, restarting xcode etc.

In Xcode 7.3.1 I can command-click FIRUserInfo and it does indeed find the header file in the pod framework as expected. But it won't compile - the last line below fails with FIRUserInfo as undeclared identifier. 

@import Firebase;
...
                [[FIRAuth auth] signInWithCredential:credential completion:^(FIRUser * _Nullable user, NSError * _Nullable error) {
                    if (error || user.providerData.count < 1) {
                        DDLogWarn(@"Firebase login after facebook failed: %@", error);
                        if( weakSelf.signInCompletionHandler ) {
                            weakSelf.signInCompletionHandler(false, false, nil);
                            weakSelf.signInCompletionHandler = nil;
                        }
                    } else {
                        FIRDatabaseReference *userRef = [[FIRDatabase database] reference];
                        userRef = [userRef child:[NSString stringWithFormat:@"users/%@", user.uid]];
                        FIRUserInfo *profile = user.providerData.firstObject;

I have the same problem of undeclared type with FIRDatabaseReference, and cannot fix it by updating the pod-file.

Finally, I find out a solution.

Google teach us to import only

import Firebase

Just add:

import FirebaseDatabase

and everything will become fine

Found the answer. Change this: FIRUserInfo *profile ... to this:

id<FIRUserInfo> profile

Man I must have been REALLY tired to miss that. Sorry for yelling, internets...

Try using 

pod 'Firebase/Auth'

In your Podfile an

@import Firebase;

Rather than the specific module - this should import the correct modules automatically.
