Subscription Question

I want to solve following situation to subscriptions.

I have a public database where all data of users gets in when they are using my CloudKit option in my App.

In this public database all Records having a unique ID representing the user.

Now i try to make subscriptions to some user ID's but i am only able to subscribe one time to the same subscription option.

What i want is that my App can subscribe to several ID's

Like App1 => subscribe to changes at all records of ID1

and also App1 => subscribe to changes at all records of ID2 etc.

Here is my function when subscribing.

/*
     **Subscribes to CloudKit Record changes**
  
     - parameter recordType: - String: *Name of the Record as String (equal to a table name)*
     - parameter predikateKey: - String: *Name of the Key for subscription (equal to column name)*
     - parameter predicate: - String: *Predicate to filter subscriptions (equal to cell value)*
     - parameter subscriptionOptions: - CKSubscriptionOptions: *Options when the subscription shoulc fire*
     - parameter alertBody: - String: *The Push Notification Message*
  
     - remark:
     Subscribes to changes of records in CloudKit Services.
     In this app all subscriptions should be filtered by predikateKey: id and predicate equal to the userId the app are subscribed to.
     */
    func subscribeToCloudKitChanges(recordType:String, predicateKey:String, predicate:String, subscriptionOption:CKSubscriptionOptions, alertBody:String) {
     
        let predicate = NSPredicate(format: "\(predicateKey) = %@", predicate)
        let subscription = CKSubscription(recordType: recordType, predicate: predicate, options: subscriptionOption)
     
        let notificationInfo = CKNotificationInfo()
        notificationInfo.alertBody = alertBody
        notificationInfo.shouldBadge = false
        notificationInfo.soundName = UILocalNotificationDefaultSoundName
     
        subscription.notificationInfo = notificationInfo
     
        publicDB!.saveSubscription(subscription, completionHandler: ({returnRecord, error in
            if let err = error {
                let title:String = eLocalization.Alert_CloudKit_Subscription_Error_Title.rawValue.localized
                let message:String = err.localizedDescription
                let dict:Dictionary<String,String> = ["Title": title, "Message": message]
                print(err.localizedDescription)
                NSNotificationCenter.defaultCenter().postNotificationName(eNSNotifications.CKmngr_SendCloudKitSubscriptionMessage.rawValue, object: dict )
            }
            else {  dispatch_async(dispatch_get_main_queue()) {
                print("CloudKit subscription success")
                let title:String = eLocalization.Alert_CloudKit_Subscription_Success_Header.rawValue.localized
                let message:String = eLocalization.Alert_CloudKit_Subscription_Success_Message.rawValue.localized + " \(predicate)"
                let dict:Dictionary<String,String> = ["Title": title, "Message": message]
                NSNotificationCenter.defaultCenter().postNotificationName(eNSNotifications.CKmngr_SendCloudKitSubscriptionMessage.rawValue, object: dict )
                }
            }
        }))
    }

getting a error message
