You'll want to allocate and initialize an empty NSMutableArray. If you're still confused, you should take another look at the video related to the code challenge.

NSMutableArray *elements = @{};

Using the following will create an empty array, no need to set the capacity to 0.

NSMutableArray *elements = [NSMutableArray array];
