Hello, we have received a crash report from AppStore connect / Xcode, TCC_CRASHING_DUE_TO_PRIVACY_VIOLATION on an iPhone 12 Pro running iOS 18.1 (unfortunately, we don't know the user and how did they get the crash)
The log mentions NSPhotoLibraryAddUsageDescription, but we are not using photo library in any shape or form, do we still need to include this key in Into.plist? And what do we put there?
Thanks!
Full log will not fit here, but here is a about half of it, with parts that mention crash (Thread 7), PhotoLibraryServicesCore, PHPerformChangesRequest determineAuthorizationStatusForChanges (Thread 4) and Binary Images, including /System/Library/Frameworks/Photos.framework/Photos /System/Library/PrivateFrameworks/PhotoLibraryServicesCore.framework/PhotoLibraryServicesCore (not sure why are they there)

UPDATE: (sorry, cannot find how to edit my post, so will comment here) we have found what the problem is, we are using the WebView from WebKit to show related Wikipedia articles, and any user who is trying to save a picture from that web-page would get this crash, unless and until we put a record with NSPhotoLibraryAddUsageDescription into Info.plist
PS to admins: if it is better to delete this post, I can do it, just thought somebody else might benefit from it, too, thanks!
