NSDictionary Challenge

Hello! I can't seem to pass the first part of this challenge. It asked me to declare an NSDictionary named album with various keys/pairs.

I've tried..

NSDictionary *album = @{ @"title":@"Abbey Road", @"author":@"The Beatles"};

and...

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

None seem to work. For the first option it says my album dictionary has not values in it. For the second, the challenge states that there are too many errors to count.

I would really appreciate any help/ clarification. Thank you!

Hello, as you can see challenge want you to Assign the following Key/pairs to it

So you should use this method:

 NSDictionary *album = @{ @"title":@"Abbey Road", @"artist":@"The Beatles" };
//make sure add a blank line at end
