I want to synchronize displaying of smart album 'Hidden' between our image picker and Photos application.
Is there a way to retrieve value of switch "Hidden Album" from settings of Photos application.
Have you looked at the PHAssetCollectionSubtype
of smartAlbumHidden
? It should provide you with the assets that are currently hidden. https://developer.apple.com/documentation/photokit/phassetcollectionsubtype/smartalbumallhidden
