推送通知已发送，但didReceiveRemoteNotification从不称为Swift

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
    // 处理接收到的远程通知
    if let aps = userInfo["aps"] as? [String: Any] {
        // 解析通知内容
        let alertTitle = aps["alertTitle"] as? String ?? ""
        let alertBody = aps["alertBody"] as? String ?? ""
        
        // 执行自定义操作
        // ...
        
        // 在通知中心显示通知
        let center = UNUserNotificationCenter.current()
        let content = UNMutableNotificationContent()
        content.title = alertTitle
        content.body = alertBody
        let request = UNNotificationRequest(identifier: "remoteNotification", content: content, trigger: nil)
        center.add(request)
    }
}
