Hello Kamal Bakhouche ,

It looks like youre missing a couple of steps. I will try to break it down for you and explain whats happening. line by line.

In line 1 we create the dictionary and assign it to the variable iceCream.

In line 2 we add another keyvalue pair to our iceCream dictionary.

In line 3 we "grab" the value of "Apple Pie" by using its Key "AP" and assign it to the constant applePie

In line 4 we are updating the value by modifying the string.

I hope this explains whats going on for you a little better.

var iceCream = ["CC": "Chocolate Chip", "AP": "Apple Pie", "PB": "Peanut Butter"]

iceCream.updateValue("Rocky Road", forKey: "RR")

let applePie = iceCream["AP"]

iceCream.updateValue("Chocolate Chip Cookie Dough", forKey: "CC")
