How to create a testflight public beta link

Here are the steps:-
I will explain these with images from WWDC video step by step. First log on to http://appstoreconnect.apple.com

1 - Log in and Navigate to the App > TestFlight Section where you can see all your build

2 - Add External Tester group
you can add on clicking Add External Testers if there is no group created
if any group is created previously then refer the image it will be new group button.

3 - Create new group and save.

4 - Now Group is created and we need to add build for testing.

5 - Click on builds section

6 - Click builds+ button and add the build for which you need to creat public link for sharing.

7 - Select the appropriate build and click ok.

8 - Go back to the tester section and click on “Enable public link”

9 - Public link is generated . You can either cop, disable or set max limit for testers who can install using this link

And this error will be shown if someone clicks on an expired testflight public beta link.

Note : The new appstore connect rest api allows us to automate tester group creation, assigning builds , making public links, adding and removing testers and updating test info. Watch WWDC video for more details WWDC Video link ref
