Benefits of Using TestFlight:

1. Early Feedback:

Enables developers to gather valuable feedback from a diverse group of testers before releasing the app to the general public.

2. Real-world Testing:

Provides the opportunity to test the app in real-world scenarios, uncovering potential issues that might not be apparent in a controlled environment.

3. Security and Privacy:

Ensures that the beta testing process is secure and respects the privacy of both developers and testers.

4. App Store Preview:

Allows developers to create a polished App Store page with screenshots, descriptions, and other information before the official release.

Requirements for Deploying Apps to TestFlight:

1. Apple Developer Account:

Ensure you have an active Apple Developer account. This is a prerequisite for accessing TestFlight.
