Create an NSDictionary called 'artDict', with the following key/value pairs: "Artist":"Dali", "Title":"The Ship", "Medium":"Oil Paint". Be sure to use the literal syntax.

First of all, you named your array atrDict instead of artDict, make sure to read the assignment carefully and check for typos.

Secondly, the trailing semicolon does belong at the end of the dictionary definition, not inside it.

Moreover, I'd recommend you use some spaces for readability :)

Therefore, the following should work:

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

Hope that helps :)
