Hi James,

You're simply setting the value of the constant applePie to the string "AP". You need to use subscripting to index into the dictionary. The very beginning of the video Modifying A Dictionary goes over this. You need to use the name of the dictionary and then square brackets with the key inside, like this:

iceCream["AP"]

The code above will return "Apple Pie", which is what you want to store in the variable applePie.

solution.swift 
let applePie = iceCream["AP"]

Make sense?

Cheers :beers:
