10,389 PointsCreate 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"]);

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"]);
Regards,
Chris
