How do I Switch From a Public App to a Private App?

Assuming there are no other issues, here’s how you can convert your public app to a private app:

1. Enroll in Apple Business Manager.
2. When the enrollment and account is confirmed, secure the registered Organization ID and Organization Name.
3. Create a new build.
4. Change the App Distribution Method to Private.
   (App Store > General > Pricing and Availability > App Distribution Methods)
5. Type in the registered Org ID and Org Name. Save.
6. Attach the new build.
7. Resubmit.
