With the new announcement, Appstore rating from app is going to be easy. Developers always had trouble and they used multiple ways to properly take the user to Appstore App by leaving their App for getting a rating from user. Now with iOS 10.3, Apple is introducing SKStoreReviewController which can be used at appropriate places from the App and user need not leave app to rate.
Another great advancement is to, reply to user reviews like Android does. Developers had real pain in understanding why certain people gave weird comments, now we have a way to know.
