iOS Object-Oriented Objective-C Getting Oriented - Object-Oriented, That Is Review NSDictionaries and NSMutableDictionaries

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

Here is my code

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

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

it works fine with Xcode but what's wrong?

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

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

Those parentheses are extraneous. Only the brackets are needed.

Hello Ge Wang,

The test is complaining about:

    NSString * favoriteArist

Notice that it is misspelled (missing t in favoriteArtist). And the test is wanting the pointer to have * next to favoriteArtist.

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



Ah, I totally missed that, Thank you so much!
