The compiler is sometimes very strict. Here is the answer:

NSDictionary *album = [[NSDictionary alloc] initWithObjectsAndKeys:@"Abbey Road", @"title", @"The Beatles", @"artist", nil];
NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];
[albumMutable setObject:@"1969" forKey:@"year"];
