Use of unresolved identifier 'FIRDatabase' when using Firebase

Question

Xcode tells me that FIRDatabaseis not an identifier. My code:

import UIKit
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApp         


        

Answer 1

1. add pod 'Firebase/Database' to your pod file
2. run the pod update command from your project dir

3. import

   `*import Firebase

   import FirebaseDatabase*`

4. Initialize and Configure your Firebase

   `*var ref: DatabaseReference!

   ref = Database.database().reference()*`
