Solution

1. Step 1: Understand TestFlight's role

   TestFlight is designed to share pre-release versions of apps with testers.

2. Step 2: Compare options

   The incorrect options describe other App Store or development tasks, not beta distribution.

3. Final Answer:

   To distribute beta versions of your app to testers before public release -> Option D

4. Quick Check:

   TestFlight = Beta distribution [OK]

Hint: TestFlight is for sharing test versions, not final release [OK]

Common Mistakes:

• Confusing TestFlight with App Store publishing
• Thinking TestFlight manages crash reports
• Assuming TestFlight creates marketing materials

easy

A. Upload your app archive to App Store Connect and add testers' emails

B. Send the app binary file directly via email to testers

C. Publish the app on the App Store and wait for approval

D. Create a provisioning profile and share it with testers

Solution

1. Step 1: Identify the correct invitation process

   TestFlight requires uploading the app to App Store Connect and inviting testers by email.

   Direct email of binaries, App Store publishing, or sharing provisioning profiles are not TestFlight steps.

3. Final Answer:

   Upload your app archive to App Store Connect and add testers' emails -> Option A

4. Quick Check:

   Upload + invite testers = Upload your app archive to App Store Connect and add testers' emails [OK]

   Testers do not see source code, App Store links, or errors if the beta is properly uploaded.

   A prompt to install the beta version of your app -> Option B

4. Quick Check:

   TestFlight app shows install prompt [OK]

Hint: TestFlight app shows install button for beta apps [OK]

2. Step 2: Exclude unrelated causes

   App Store listing, iOS version, or push notifications do not block TestFlight visibility.

3. Final Answer:

   You forgot to add testers' email addresses in App Store Connect -> Option C

4. Quick Check:

   Missing testers' emails = no app visible [OK]

Hint: Always add testers' emails in App Store Connect [OK]

Common Mistakes:

• Assuming app listing is required for TestFlight
• Blaming testers' iOS versions prematurely
• Confusing push notification settings with TestFlight access
