Managing App Store Ratings and Reviews
iOS 10.3 introduces a new way to ask customers to provide App Store ratings and reviews for your app. Using the
SKStoreReviewController API, you can ask users to rate or review your app while they're using it, without sending them to the App Store. You determine the points in the user experience at which it makes sense to call the API and the system takes care of the rest.
When iOS 10.3 ships to customers, you will be able to respond to customer reviews on the App Store in a way that is available for all customers to see. (This feature will also be available on the Mac App Store.)
