Apple Announces TestFlight Group Testing
Apple has today announced to developers TestFlight Groups. This allows developers to create a group of testers for their application. Rather than having to add a tester to your app one by one, you can create a group of people that you can assign to every app that you want.
You just file people under a certain group and add then as testers. This allows developers to send out testing invites much quicker. They can always have a pre-determined list of people who will test an application. Developers can learn more about the new TestFlight Groups here.
