help for the task 2

// IceCream var iceCream = ["CC": "Chocolate Chip", "AP": "Apple Pie", "PB": "Peanut Butter"] iceCream.updateValue : ["Rocky Road", "RR"]

It might help to check out the documentation for the Dictionary.updateValue() method. Here's a link to it: updateValue(_:forKey:).
It looks like you're really close. All you need to do is put your values into the method parameters. For example, if I wanted to add "Cookie Dough" for the key "CD" I'd call the method like this:
iceCream.updateValue("Cookie Dough", forKey: "CD")
There's also a shorthand way to do this by using subscript syntax:
iceCream["CD"] = "Cookie Dough"

It kind of looks like you're trying to combine the two ways to solve this part of the challenge.
updateValue is a method. The syntax for using the method was given in the problem description:
updateValue(Value, forKey: Key). This looks like:
var iceCream = ["CC": "Chocolate Chip", "AP": "Apple Pie", "PB": "Peanut Butter"] iceCream.updateValue("Rocky Road", forKey: "RR")
You could also solve this by using simple subscript syntax:
var iceCream = ["CC": "Chocolate Chip", "AP": "Apple Pie", "PB": "Peanut Butter"] iceCream["RR"] = "Rocky Road"
Both ways accomplish the task at hand! Happy coding!
