ios – 使用未解析的标识符’FIRApp’

我已经使用可可豆荚在我的iOS应用程序中实现了Firebase.问题是当我尝试配置firebase时,我收到此错误使用未解析的标识符’FIRApp’.当我在appdelegate文件中使用代码FIRApp.configure()时,会发生此错误.谁能帮我这个？

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
  }
}

我遵循了Firebase指南https://firebase.google.com/docs/ios/setup#initialize_firebase_in_your_app

这是pod文件
