Somethings wrong with this challenge

The code i entered : NSDictionary *album = @{@"title":@"Abbey Road",@"artist":@"The Beatles"}; NSMutableDictionary *albumMutable =[[NSMutableDictionary alloc] initWithDictionary:album];

The challenge claims this is wrong, but gives no reason. The code compiles just fine in xCode...

the challenge expects you to use the dictionaryWithDictionary convenience constructor. 

NSDictionary *album = @{@"title":@"Abbey Road",@"artist":@"The Beatles"};
NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];
