Area: Music Summary: When adding a folder to the media library, there's no documented way to discern between a regular playlist and a playlist folder. There's also no documented way to get the parent folder of a playlist or children of a folder. There do seem to be an undocumented keys available on the MPMediaPlaylist class. 1. @"isFolder" which is a BOOL, 0 if not a folder or 1 if the object is a folder 2. @"parentPersistentID" which is the persistentID of the objects parent folder Please add these to the documented keys and properties. Steps to Reproduce: Create a folder in your media library Create some playlists in that folder MPMediaQuery *query = [MPMediaQuery playlistsQuery]; NSArray *collections = query.collections; [collections enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) { MPMediaPlaylist *playlist = obj; NSLog(@"playlist name = %@", playlist.name); NSLog(@"playlist isFolder = %@", [playlist valueForProperty:@"isFolder"]); NSLog(@"playlist parentPersistentID = %@", [playlist valueForProperty:@"parentPersistentID"]); }]; Expected Results: MPMediaPlaylistPropertyIsFolder and MPMediaPlaylistPropertyParentPersistentID Actual Results: No documented keys or properties for these values but it is possible to retrieve them Version: iOS 10.1.1 & 9.3.5 Notes: Xcode 8.1 Configuration: iPhone 7 Plus 10.1.1, iPhone 6 9.3.5
