Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage
We noticed that your app requests the user’s consent to access their camera but does not clarify the use of this feature in the permission modal alert.
To resolve this issue, please revise the permission modal alert to specify why the app is requesting access to the user’s camera.
The permission request alert should specify how your app will use this feature to help users understand why your app is requesting access to their personal data.
For additional information and instructions on configuring and presenting an alert, please review the Requesting Permission section of the iOS Human Interface Guidelines and the Information Property List Key Reference. You may also want to review the Technical Q&A QA1937: Resolving the Privacy-Sensitive Data App Rejection page for details on how to provide a usage description for permission request alerts.
