I've been having trouble uploading my app to the app store using application loader.It accepts the app to start with, but 5 minutes after submitting, I get an email saying:Missing Info.plist key - This app attempts to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data.However, my info.plist has this key in it<key>NSPhotoLibraryUsageDescription</key><string>$(PRODUCT_NAME) uses photos</string>Can anybody explain why this isn't working?
