swift - 无法将模块 'fireBaseDatabase' 加载为 'FirebaseDatabase'

Question

所以，我是 Firebase 的新手，我正在关注这个人关于如何将 Swift 应用连接到 Firebase 的教程，这对他来说完全没问题。但是当我尝试导入“FirebaseDatabase”时，它给了我这个错误；

无法将模块“fireBaseDatabase”加载为“FirebaseDatabase”

我想知道如何解决这个问题。谢谢。

这是我的 podfile；

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'FIRBaseQuickStart' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for FIRBaseQuickStart

    pod ‘Firebase’
    pod ‘Firebase/Database’

end

现在，当我尝试运行该应用程序时，它显示“线程 1:信号 SIGABRT”。

import UIKit
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        FirebaseApp.configure()

        return true
    }

    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    }

    func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }


}

它在类声明行上给了我错误。这太令人沮丧了。

如果您使用最新 (4.0) 版本的 Firebase，则只需使用 import Firebase，正如我从文档中了解到的那样。

对于数据库引用:

var ref: DatabaseReference!

ref = Database.database().reference()

可以找到here

尝试一下。希望对您有所帮助。
