Upgraded Firebase - Getting error on FirebaseApp.configure()

Question

I upgraded Firebase today and now I am having a very unusual problem

Use of unresolved identifier FirebaseApp.

I have done everything as per the documentation provided by firebase here. I have insert GoogleService-Info.plist on my project and pod i have install are as follows:

pod 'Firebase/Core
pod 'Firebase/Database
pod 'Firebase/Messaging

I am using XCode 7.3.1 and my deployment target is 9.0

Any insight you can give is greatly appreciated! Thank you!

Answer 1

It seems this is a potential bug in the latest release.

Try specifying import FirebaseCore instead.

Answer 2

I had the same problem. They have renamed it to FIRApp.

Use FIRApp.configure() instead

Answer 3

On the terminal, run

pod update

solves the problem

Answer 4

I had a similar issue. Try deleting and uploading you Google file this way:

Instead of dragging the Google file directly into your Xcode project, right click the folder (inside your Xcode project) that you would like to save the Google file and click "Add Files to '[App Name]'..." and add GoogleService-info.plist that way. Also make sure the file is called "GoogleService-info.plist".

Answer 5

1. Install relative Firebase packages

   pod 'Firebase/Analytics'
   

2. Import Firebase in Xcode

   #import <Firebase.h>
   

3. Add firebase configure. I attached screenshot

   if ([FIRApp defaultApp] == nil) {
       [FIRApp configure];
   }
