Estoy haciendo el seguimiento de comercio electrónico de google analytics. Y cuando realizo cualquier envío de producto o transacción, ese valor no se actualiza en mi consola de Google Analytics.

Aquí mi código:

   static func sendGAEvent(_ categoty: String, params: [String : NSObject]){

        let tracker = GAI.sharedInstance().tracker(withTrackingId: UA 234234-4)

        if let tracker = tracker {

            for (k, _) in params{
                let key = k
                let value = params[k]
                if let val = value as? String {
                    tracker.set(key, value: val)
                }
            }

            if let screenTitle = params[“screen_title” as? String{

                tracker.set(kGAIScreenName, value: screenTitle)

                guard let builder = GAIDictionaryBuilder.createEvent(withCategory: categoty, action: screenTitle, label: screenTitle, value: 0)
                    else
                {
                    return
                }



                tracker.send(builder.build() as [NSObject:AnyObject])

            }


            if  categoty ==  “shoping_cart”{

                let Tid  = params[mob_no] as? String
                let TRevenue  = params[amount] as? String    //  it will be amount of product getting from params
                let TCurrencyCode  = params[code] as? String   //  it will be code of product  from params

                tracker.set(kGAITransactionId, value: Tid)
                tracker.set(kGAITransactionRevenue, value: TRevenue)  
                tracker.set(kGAICurrencyCode, value: TCurrencyCode)

                guard let maker = GAIDictionaryBuilder.createTransaction(withId: Tid, affiliation: optional, revenue: 80, tax: 0, shipping: 0, currencyCode: TCurrencyCode)
                    else
                {
                    return
                }


                   print("done updating first")     
                tracker.send(maker.build() as [NSObject:AnyObject])
                print("done updating second")


            }



        }

    }

Si algún experto en google analytics por favor, dame alguna solución .. !!

Gracias !
