A very common way of sharing iOS builds is through TestFlight. The following information assumes that the user has already installed the TestFlight app on their mobile device.
1. Installing a build using Testlio shared test AppleID
Shared AppleID usually means that Testlio has provided a client an AppleID that client has shared their app to. Testlio will use the same AppleID to make the app available to our testers. Why we use this option is that sending our testers personal AppleIDs would be a time consuming effort for all parties involved.
Open TestFlight app
Make sure you have logged out from your personal account or any other project shared test accounts
Login using shared AppleID provided by Testlio
It could be shared in ‘Instructions to testers’ section or Rocket.Chat
Apple wants to force us to use 2FA but we do not want to use that, following the guide will help you not to do that - when you’re prompted with this, please select ‘Don’t upgrade’
Activities after you have completed testing
Tester always must log out after testing
2. Installing the build using a public link
When a public link is used, that means that testers can use their own AppleIDs to ‘sign up’ for testing since the invite link is public.
Click the public link shared
It could be shared in ‘Instructions to testers’ section or RocketChat
