Hey there Travis!

In this challenge you are asked to separate the dictionary values into the different arrays. You need to evaluate the keys using a switch to append the values to those arrays.

var someCapitals: [String] = []
let world = ["TRH" : "Treehouse"]

switch key {
   case "TRH":
      someCapitals.append(value)
   default:
      ...
}

Hope it helps you a bit.
