来自推送通知的用户信息在苹果手表目标中为空

Question

嗨，我们有一个项目，其 QA 目标和生产目标是用 swift 编写的，而 watch 目标是用 swiftui 编写的。在第一个目标中，推送通知运行良好，但在 watch 目标中，推送通知确实收到了调用的函数，但得到的用户信息为空。我不明白可能是什么问题。可能缺少某个定义，或者由于对目标的不正确管理而产生了问题。因为目前大部分与Push相关的代码都在App Delegate中请帮帮我。谢谢

这是具有推送通知委托功能的类：

import UserNotifications
import SwiftUI

class NotificationCenter: NSObject, ObservableObject {
    @Published var request: UNNotificationRequest?
    override init() {
        super.init()
        setUpNotificationPreferences()
    }
    
    func setUpNotificationPreferences() {
        let center = UNUserNotificationCenter.current()
        center.delegate = self
        center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
            if granted {
                let category = UNNotificationCategory(identifier: "SAVE_CATEGORY", actions: [], intentIdentifiers: [], options: [])
                center.setNotificationCategories(Set([category]))
            } else {
                print("No permission" + error.debugDescription)
            }
        }
    }
}

extension NotificationCenter: UNUserNotificationCenterDelegate  {
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        self.request = notification.request
        completionHandler([.alert, .sound, .badge])
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        self.request = response.notification.request
        completionHandler()
    }
}
