升级到 Xcode 12.5 后在构建时收到错误，关于注册通知 (Swift)

如何解决升级到 Xcode 12.5 后在构建时收到错误，关于注册通知 (Swift)

升级到 Xcode 12.5 后，我的项目无法构建，我的 AppDelegate 出现错误。我可以在升级前确认没有问题，而且我无法在任何地方找到解决此问题的文档。提前致谢！

AppDelegate 代码：

import UIKit
import Firebase
import IQKeyboardManagerSwift
import FirebaseMessaging

@main
class AppDelegate: UIResponder,UIApplicationDelegate {
    
    let gcmMessageIDKey = "gcm.message_id"
    
    func application(_ application: UIApplication,didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        
        FirebaseApp.configure()
        
        IQKeyboardManager.shared.enable = true
        
        Messaging.messaging().delegate = self        
        
        if #available(iOS 10.0,*) {

          UNUserNotificationCenter.current().delegate = self

          let authOptions: UNAuthorizationoptions = [.alert,.badge,.sound]
          UNUserNotificationCenter.current().requestAuthorization(
            options: authOptions,completionHandler: {_,_ in })

        } else {

          let settings: UIUserNotificationSettings =
          UIUserNotificationSettings(types: [.alert,.sound],categories: nil)
            application.registerUserNotificationSettings(settings)
            
        }

        application.registerForRemoteNotifications()

        func application(_ application: UIApplication,didReceiveRemoteNotification userInfo: [AnyHashable: Any],fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
          
          if let messageID = userInfo[gcmMessageIDKey] {

            print("Message ID: \(messageID)")

          }

          print(userInfo)

          completionHandler(UIBackgroundFetchResult.newData)

        }
        
        return true
    }
}

错误：

1)

application.registerUserNotificationSettings(settings)

“'(UIApplication,[AnyHashable : Any],@escaping (UIBackgroundFetchResult) -> Void) -> ()' 类型的值没有成员 'registerUserNotificationSettings'”

2)

application.registerForRemoteNotifications()

“'(UIApplication,@escaping (UIBackgroundFetchResult) -> Void) -> ()' 类型的值没有成员 'registerForRemoteNotifications'”
