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:

Answer 1

first make sure your Firebase version is 3 by use console to entering your project file and use pod update order to update your Firebase version to 3

Answer 2

Try removing the pods from the podfile and then do a 'pod install'. Add the pods back and then do another 'pod install'. Clean your workspace and then build it. It took me a few tries but that ended up working for me.

Answer 3

If you are using ReactNative > 0.62, make sure that you put in AppDelegate.m

#import <Firebase.h>

Before:

#ifdef FB_SONARKIT_ENABLED

Answer 4

Solve this problem like this:

import FirebaseAnalytics

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

Thanks.

Answer 5

In AppDelegate.m file, import this line: #import <Firebase.h> before #ifdef FB_SONARKIT_ENABLED line.

Answer 6

All the other answers are spot on, but it sounds like you've got that stuff covered. Make sure you're using CocoaPods 1.0 (or above) and have specified use_frameworks! in your Podfile.

If you are upgrading, its worth clearing our your Pods/ directory first and possibly running pod deintegrate to get back to a zero state.
