Hi Francis,

The key/value pairs are stored backwards, just as the init method states ... value (object) first, then the key. So, your code is pretty much what seems sensible - you just need to reverse each pair (and uncaptialize @"title")

NSDictionary *album = [[NSDictionary alloc] initWithObjectsAndKeys:@"Abbey Road", @"title", @"The Beatles", @"artist", nil];

I hope that makes sense!

Steve.
