Hello :

I will guide you a bit through the code so you can understand it a bit. But will not give you the complete answer so that you can solve it yourself. This way, it helps you a bit more and not just get the answer.

The challenge is asking you to Switch on the key value. You are switching in world. Also the switch should look something like this.

   switch key {
   case key "USA":
   array.append(value)
   default: break
   }

Good luck, if you need more help let me know.
