iRate Delegates are Not getting Called

[Abhishek-NickelFox]

I have added code in AppDelegate and added iRateDelegate also

func iRateUserDidAttemptToRateApp() {
Analytics.track(event: .UserRatingNow)
}

func iRateUserDidDeclineToRateApp() {
Analytics.track(event: .UserDeclinedToRateApp)
}

But these 2 delegates are not getting called
