I do not the understand the "completion: completion" part in this video

https://teamtreehouse.com/library/network-programming-with-swift-2/implementing-a-forecast-client/from-json-to-currentweather

What is going on here? Are we bubbling up the APIResult?

Theres a part where he writes completion: completion, and i have struggled for a week to understand the completion handler. I can understand it in simple forms, and i understand that when you write completion(x), you are sending something into the closure you are making, but i dont understand "completion: x"

Can someone explain?

Edit: Changed question, provided link ( i clicked "ask question" under the video so i thought it would be posted there, sorry ).
