1.TestFlight是什么？
1) The TestFlight app allows you to install and beta test apps on your iOS, tvOS and watchOS devices.
After a developer invites you to beta test their apps, you can install new versions as they become available.
2) TestFlight also allows you to provide valuable feedback to developers on the features you are testing.
To start testing:
-All the app developer needs is your email address to send you an invitation
-Then accept the invitation either in the TestFlight iOS app or with a redemption code found via a link in the beta invitation
-Once accepted you can install the prerelease build
-The TestFlight app will notify you when new builds are available
-To update to the latest build, simply tap Update
Developers can invite TestFlight Beta Testers on the iTUnes Connect website:
-Create a version of your app and upload new builds
-Choose which prerelease version of your app you wish to release to testers
-Invite new testers by simply providing their email address
