Firebase + GTM + GA实施问题(Firebase + GTM + GA implementation issue)

 我正在使用iOS Swift 3并尝试在Firebase中跟踪屏幕视图，并将这些数据通过GTM推送到GA中。 
 
 我的问题是我无法从推入GA的“screen_view”事件中获取屏幕名称。 
 
 在firebase中，初始自动屏幕视图命中没有屏幕名称，只有屏幕类，因此我使用Analytics.setScreenName设置屏幕名称并覆盖屏幕类。 
 
 但是，这会导致Firebase中的两次点击，一次自动没有屏幕名称，一次手动触发屏幕名称。 
 
 另外，我想将事件中的屏幕名称作为屏幕视图类型传递给GA。 我将GTM中的screenName字段设置为变量。 
 
 我已经尝试了变量的各种事件参数 
 
 
 
 “firebase_screen”：结果未在GA中找到和（未设置） 
 
 
 “_sn”：在xCode调试中导致“无效的事件参数” 
 
 
 所以我猜所有以_开头的参数都在Firebase中保留。 那么如何从firebase获取保留的事件参数到GA。 例如，我可能希望将App版本存储在自定义维度中。 
 
 这里最大的问题是从GTM到GA的屏幕视图中没有显示屏幕名称。 

I am using iOS Swift 3 and trying to track screen views in Firebase and push those data into GA with GTM. 
 
My issue is that I cannot get the screen name from "screen_view" events pushed into GA. 
 
In firebase, the initial automated screen view hit has no screen name and only screen class so I used Analytics.setScreenName to set the screen name and override the screen class.
 
However this causes two hits in Firebase, one automated with no screen name and one manually triggered with screen name.
 
Also, I want to pass the screen name from the event into GA as a screen view type. I set the screenName field in GTM to a variable.
 
I have tried various event parameters for the variable
 
 
 
"firebase_screen" : results in not found and (not set) in GA
 
 
"_sn" : results in "invalid event parameter" in xCode debug
 
 
So I guess all the parameters that start with _ are reserved in Firebase. So how do I get the reserved event parameters from firebase into GA. For example, I may want to store the App Version in a custom dimension for something. 
 
The biggest problem here is the screen name not picking up in the screenview hit from GTM to GA.
