Apple updated Ratings and Review Policy

You can ask users to rate and review your app at appropriate times throughout the user experience. Make the request when users are most likely to feel satisfaction with your app, such as when they've completed an action, level, or task.
Give users an easy way to provide feedback on the App Store without leaving your app using the SKStoreReviewController API. You can prompt for ratings up to three times in a 365-day period.

Apple App Store Ratings and Reviews

When you call SKStoreReviewController.requestReview() while your app is still in development mode, a rating/review request view is always displayed so that you can test the user interface and experience. However, this method has no effect when you call it in an app that you distribute using TestFlight.

Animations with Lotti for SVG-like Animations created by After Effects for iOS, Android and React Native by AirBnB

Lottie AirBnB: Behind the scenes of our new open-source animation tool.
Lottie is an iOS, Android, and React Native library that renders After Effects animations in real time, and allows native apps to use animations as easily as they use static assets. Lottie uses animation data exported as JSON files from an open-source After Effects extension called Bodymovin. The extension is bundled with a JavaScript player that can render the animations on the web.

Lottie also has several features built into its API to make it more versatile and efficient. It supports loading JSON files over the network, which is useful for A/B testing. It also has an optional caching mechanism, so frequently used animations, such as a wish-list heart, can load a cached copy each time. Lottie animations can be driven by gestures using the animated progress feature, and animation speed can be manipulated by changing a simple value. iOS even supports adding additional native UI to an animation at runtime, which ca…

Texture: Keeps the most complex iOS user interfaces smooth and responsive.


Texture is an iOS framework built on top of UIKit that keeps even the most complex user interfaces smooth and responsive. It was originally built to make Facebook's Paper possible, and goes hand-in-hand with pop's physics-based animations — but it's just as powerful with UIKit Dynamics and conventional app designs. More recently, it was used to power Pinterest's app rewrite.

As the framework has grown, many features have been added that can save developers tons of time by eliminating common boilerplate style structures common in modern iOS apps. If you've ever dealt with cell reuse bugs, tried to performantly preload data for a page or scroll style interface or even just tried to keep your app from dropping too many frames you can benefit from integrating Texture.
