How to access value in NSDictionary?

I am unable to access a value in a NSDictionary.

Currently, what I have is NSString * favoriteArtist = [artDict valueForKey: @"Artist"];

variable_assignment.mm 
NSDictionary * artDict = @{ @"Artist":@"Dali", @"Title":@"The Ship", @"Medium":@"Oil Paint"};

NSString * favoriteArtist = @[artDict @"Artist"];

Eric, very close:

NSDictionary * artDict = @{ @"Artist":@"Dali", @"Title":@"The Ship", @"Medium":@"Oil Paint"};

NSString *favoriteArtist = [ artDict valueForKey: @"Artist"];
