Hello fellow developers, this is my first app submission and my app got rejected with the following message. I don't quite understand why my app was rejected and how I can fix the problem. any suggestions ?
Your app uses public APIs in an unapproved manner, which does not comply with guideline 2.5.1 of the App Store Review Guidelines.
Specifically, your application allows users to import photos, videos and notes to a private secret vault that only the user has access to.
Since there is no accurate way of predicting how an API may be modified and what effects those modifications may have, Apple does not permit unapproved uses of public APIs in App Store apps.
