Use of unresolved identifier 'FIRDatabase' when using Firebase

Solution 1
You need to add
pod 'Firebase/Database'
to your pod file as explained here
https://firebase.google.com/docs/database/ios/start
Here you can find which pod includes which feature Pods and Features
Solution 2
What worked for me, in addition to adding pod 'Firebase/Database'
, was (which is missing from the current docs):
import FirebaseDatabase
Tested with Xcode 7.3.1, CocoaPods 0.39.0 & 1.0.1 on macOS 10.11.5. To make sure you're doing this correctly, please make sure your Podfile.lock looks something like:
PODS:
...
- FirebaseDatabase (3.0.1):
- FirebaseAnalytics (~> 3.2)
...
P.S. I ran into CocoaPods issues that forced me to delete the derived data folder, so try that as well.
Solution 3
New syntax for using FIRDatabase:
Database.database().reference()
Solution 4
This worked for me
- Add
pod 'Firebase/Database'
to your pod file - pod install
- Open XCode and Rebuild Project

Xcode tells me that
FIRDatabase
is not an identifier. My code:import UIKit import Firebase @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { FIRApp.configure() FIRDatabase.database().persistenceEnabled = true // Use of unresolved identifier 'FIRDatabase' return true } }
I am using:
Xcode 7.2.1, Firebase 3.0.2, OSX 10.10.5
Podfile content:
source 'https://github.com/CocoaPods/Specs.git' platform :ios, '8.0' use_frameworks! target 'myapp' do pod 'IQKeyboardManagerSwift', '<= 4.0.0' pod 'JSQMessagesViewController', '<= 7.3.1' pod 'Firebase' end
