This is a kind of question regarding best practice.
I am using VIPER architecture in my iOS project. I use haptic feedback for some use cases. Where would be the best place to invoke UINotificationFeedbackGenerator in VIPER? I believe it is View.
You should place it in presenter , why ?
View => It's not a view
Interactor => It doesn't involve intercalation with data
Entity => It's not a model
Router => It's not used to navigate to other pages
