Apple today seeded the seventh beta of iOS 10.3 to developers. This comes a few days after the sixth build. In this version of iOS we find Find my AirPods, a new file structure for better performance, tweaked app animations, and new in-app review request prompts.
To get this version developers can go to Settings and find it under software updates. If you don’t have the best testing profile installed you can go to the Apple Developer Center and get it from there.
