Adding App Events in iOS app produces undeclared identifier 'AppEvent'

Question

I am trying to add facebook app events, and I installed FacebookSDK. Then I have next code:

import FacebookCore

static func logViewContentEvent(contentType : String, contentData : String, contentId : String, currency : String, price : Double) {
        let params : AppEvent.ParametersDictionary = [
            .contentType : contentType,
            .content : contentData,
            .contentId : contentId,
            .currency : currency
        ]
        let event = AppEvent(name: .viewedContent, parameters: params, valueToSum: price)
        AppEventsLogger.log(event)
    }

But I get error from the title. What I am doing wrong, and why this type is missing?

It's a knowed facebook annoying issue.

Before FBSDK 5.0.1 your code works well. After, you can change your code with for example:

static func logViewContentEvent(contentType : String, contentData : String, contentId : String, currency : String, price : Double) {
        let params =  [
            "contentType": contentType,
            "content" : contentData,
            "contentID" : contentId,
            "currency" : currency
        ]
        AppEvents.logEvent(AppEvents.Name(rawValue: "viewedContent"), valueToSum: price, parameters: params)
    }
