swift - 错误 : no such module 'FirebaseInstanceID' on ios

Question

我正在尝试运行我的代码并不断告诉我

error: no such module 'FirebaseInstanceID'
    import FirebaseInstanceID

我在 AppDelegate.swift 中的代码

import UIKit
import Flutter

import Firebase
import FirebaseAuth
import UserNotifications
import FirebaseInstanceID

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
  
   override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        let firebaseAuth = Auth.auth()
        firebaseAuth.setAPNSToken(deviceToken, type: AuthAPNSTokenType.unknown)

    }
    override func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        let firebaseAuth = Auth.auth()
        if (firebaseAuth.canHandleNotification(userInfo)){
            print(userInfo)
            return
        }
    
    }
}

我认为我的 pod 中缺少它，我不知道如何将它安装到我的 pod 文件中。

FirebaseInstanceID 现在已弃用，这就是出现此错误的原因。删除 import FirebaseInstanceID 来自您的 AppDelegate.swift 而是添加 import FirebaseMessaging 因为 FCM token 现在直接在 Messaging 实例上提供。现在替换的代码InstanceID 在 didRegisterForRemoteNotificationsWithDeviceToken 有了这个

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    Messaging.messaging().apnsToken = deviceToken
    Messaging.messaging().token { (token, error) in
        if let error = error {
            print("Error fetching remote instance ID: \(error.localizedDescription)")
        } else if let token = token {
            print("Token is \(token)")
        }
    }
}
