I'm Not Sure How To Solve This Problem

I've tried a variety of options including:

NSDictionary *album = @{ @"title":@"Abbey Road", @"artist":@"The Beetles" };

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

I'm currently getting that my album has no definitions. I'm not sure what it is asking for.

your first solution will work, however you misspelled the artists name which is causing the errors. Its "The Beatles" not "The Beetles"

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

the second one will work as well, but you also have the incorrect artist name. It should be "The Beatles" not "Beatles"

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

so you just had some minor typos that were causing your code to fail

haha thank you, I had 3 iOS developers in my company look at the code and it took us 25 minutes to realize that was the error.

Thank you :)
