Use of unresolved identifier 'FIRApp'

Question

I have implemented Firebase in my iOS App using cocoa pods. The problem is when i try to configure firebase, i get this error Use of unresolved identifier 'FIRApp'. This error occurs when i use the code FIRApp.configure() in appdelegate file. Can anyone help me with this?

import UIKit
import AWSCore
import GoogleMaps
import Firebase
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

  var window: UIWindow?

  let defaults = NSUserDefaults.standardUserDefaults()

  func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    // Use Firebase library to configure APIs
    FIRApp.configure()
    return true
  }
}

I have followed Firebase Guide https://firebase.google.com/docs/ios/setup#initialize_firebase_in_your_app

Here is the pod file

# Uncomment this line to define a global platform for your project
platform :ios, '8.0'
use_frameworks!

target 'xxxx' do
     pod 'SwiftyJSON', :git =>       'https://github.com/SwiftyJSON/SwiftyJSON.git'
     pod 'DKChainableAnimationKit'
     pod 'Charts'
     pod 'JVFloatLabeledTextField'
     pod 'AWSAutoScaling'
     pod 'AWSCloudWatch'
     pod 'AWSCognito'
     pod 'AWSDynamoDB'
     pod 'AWSEC2'
     pod 'AWSElasticLoadBalancing'
     pod 'AWSKinesis'

Simple solution is just import firebase before this line

#ifdef FB_SONARKIT_ENABLED

Answer 2

I've Tried all the answers but after 2 hours of headache...I found this

In AppDelegate.m file, you should import firebase like #import <Firebase.h> before #ifdef FB_SONARKIT_ENABLED line.

As I understand, You probably get success on dev build because FlipperKit libraries are used for debugging and this #ifdef FB_SONARKIT_ENABLED if condition is satisfied. When you try to archive it will not be imported and the variables will be undeclared because #import <Firebase.h> remains in that if condition.

Answer 3

FIRApp is available in Firebase 3.x or later.

This happens when you can't update from old versions of Firebase say 2.x to 3.x. This has been already answered here- Firebase Upgrading From 2.5.1 to 3.2.1

and How to upgrade new Firebase app from exist old app?

Key is-

pod update

You need to run pod update once before installing the Firebase pod and it will install the correct version when you do it next time.

I found out what was causing the problem. I was using an older version of cocoa pods. When i updated the cocoa pods version to the latest one, the error was rectified. Thanks.

just run this.

sudo gem update cocoapods
