Challenge Task 2 of 4
An ice cream shop with only three flavors would be somewhat limited. Let's add another flavor to the list!
Add the value, "Rocky Road", for the key "RR" to the iceCream dictionary.
You can either add it using subscript syntax or the method updateValue(value: Value, forKey key: Key). The method takes a value and a key. Example: updateValue("Pistachio", forKey: "PI")
I am Stak ....
// Enter your code below
var iceCream = ["CC": "Chocolate Chip",
"AP": "Apple Pie",
"PB": "Peanut Butter"
"RR": "Rocky Road"]
updateValue (value: Value, forKey key: Key)
updateValue ("Pistachio", forKey: "PI")

15,789 PointsI did this a different way.
First make sure that your dictionary looks like this:
var iceCream = ["CC": "Chocolate Chip",
"AP": "Apple Pie",
"PB": "Peanut Butter"]
Then, using the subscript syntax I added the value for Rocky Road as follows:
iceCream["RR"] = "Rocky Road"
The other way to do this is:
iceCream.updateValue("Rocky Road", forKey: "RR")
Does this help? I notice that your code looks like you may be on a different stage, if this is the case let me know and I'll give it another try!
