Swift Question

Use of unresolved identifier 'FIRDatabase' when using Firebase

Xcode tells me that

is not an identifier.
My code:

import UIKit
import Firebase

class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
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'

target 'myapp' do
pod 'IQKeyboardManagerSwift', '<= 4.0.0'
pod 'JSQMessagesViewController', '<= 7.3.1'
pod 'Firebase'
