如何使用google tag manager v5在swift中编码，尤其是增强型电子商务部分？

我正在尝试将gtm v5用于Swift，但我发现它不起作用

它没有向谷歌分析发送任何数据，但同时也没有给我错误。我已经仔细检查了GTM，所有内容都与Google Tag Manager文档中的相同

   override func viewDidLoad() 
   {
    super.viewDidLoad()

    let  product1 : [String : Any] = [
        AnalyticsParameterItemID : "sku1234", // ITEM_ID or ITEM_NAME is required.
        AnalyticsParameterItemName : "Android Jogger Sweatpants",
        AnalyticsParameterItemCategory : "Apparel/Men/Pants",
        AnalyticsParameterItemVariant : "Blue",
        AnalyticsParameterItemBrand : "Google",
        AnalyticsParameterPrice : 39.99,
        AnalyticsParameterCurrency : "USD",  // Item-level currency unused today.
        AnalyticsParameterQuantity : 1
    ]

    let items : Array = [product1]

    let ecommerce : [String : Any] = [
        "items" : items,
        "screenName" : "Thank you page",
        AnalyticsParameterItemList : "Search Results", // List name.
        AnalyticsParameterTransactionID : "T12345",
        AnalyticsParameterAffiliation : "Google Store - Online",
        AnalyticsParameterValue : 75.98, // Revenue.
        AnalyticsParameterTax : 3.80,
        AnalyticsParameterShipping : 5.34,
        AnalyticsParameterCurrency : "USD",
        AnalyticsParameterCoupon : "SUMMER2017"
    ]

    Analytics.logEvent(AnalyticsEventEcommercePurchase, parameters: ecommerce)

    print("Success!")
}
