Create an NSString variable called 'favoriteArtist' and assign it the value found for the key 'Artist', in the 'artDict'

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

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

//What am I doing wrong?)//

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

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

Your artDict is fine, though I would remove that last comma after @"Oil Paint" for personal aesthetic reasons.

For favoriteArtist, you should use the valueForKey: method on artDict.

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

I hope this helps!
