Hello there!
I am trying to implement this step of the iOS - Objective C https://api.qualtrics.com/ZG9jOjgwNTgzNjU-app-feedback-i-os-api-reference#evaluateproject, but when implementing, I get the error "No visible @interface for 'Qualtrics' declares the selector 'displayWithViewController'.
Implementing as in the guide shows that there is no method to call, the only way to make it work is by implementing a closure that takes an NSNumber as parameter.
As a result, in any call, is a null pointer exception.
Do you know what I am missing here?
