How to preview your iOS app with Apple's TestFlight app

In order to preview your app prior to submission to Apple for review, you will need to use Apple's TestFlight app. Users will need to be added to your App Store Connect account before they can preview the app using TestFlight. This article will cover how to invite a user's Apple ID to your App Store Connect account, add them to an Internal Testing group, and how to redeem a code in order to preview the app. 

  • Prior to inviting users to App Store Connect, advise them they will need to download the TestFlight app from the App Store.

Invite a user to App Store Connect

  1. Log into your App Store Connect, click the Users and Access icon.
  2. Click  blue_cross-2 to add a new user.

  3. The "New User" pop-up will open. Enter the user's information:
    • First name
    • Last Name
    • Email (Apple ID)
  4. Roles: Choose a role for the user. Roles that can use TestFlight are Admin, App Manager, Developer, or Marketing. The roles each have different account permissions. If you are unsure which role to give your tester, use the Marketing role as this role has the least amount of permissions. More about Program Roles can be found here:
  5. Additional Resources: If the user is being added just for the use of TestFlight then no other resources are required.
