This means that developers can get feedback from testers on features like SiriKit, Push Notifications for tvOS, new iOS Extension APIs, and more.
What's New In This Version:
● All beta apps on iOS 10 now include a 3D Touch Quick Action so your testers can provide feedback by pressing your Home screen icon.
● Stability and performance improvements
● There is a known issue on iOS 10 beta where beta apps installed by TestFlight are replaced by the App Store version if Automatic App Updates is turned on. If you experience this issue, disable Automatic App Updates. This issue will be addressed in an upcoming release.
You can download TestFlight from the App Store for free.
