Inside of my info.plist file:

<key>NSPhotoLibraryUsageDescription</key>
<string>This app uses the device's library to upload photos.</string>

How can I be more detailed than this?

The issue is the user can upload photos for many different purposes:

Profile pictures, attach pictures to messages, etc.

So do I have to include all purposes in this one message?

I’ve seen other apps with this exact same string message. “Upload photos” seems simple, clear and straight to the point. Anything I can do to get accepted without confusing the user with all different purposes in a single message?
