UNUserNotificationCenterDelegate与didReceiveRemoteNotification之间的差异

Question

[当我们同时实现didReceiveRemoteNotification和UNUserNotificationCenterDelegate方法时，iOS的行为-

  optional public func userNotificationCenter(_ center: 
  UNUserNotificationCenter, didReceive response: UNNotificationResponse, 
  withCompletionHandler completionHandler: @escaping () -> Swift.Void)

根据文档，receiveRemoteNotification已过时，但如果应用程序已实现两种委托方法，则哪个对象可以在XCode 8（Swift 3）上同时调用iOS 10应用程序和iOS 9应用程序？
