I'm not sure what operation they want me to execute for the while statement. Is it for the variable above?

Am I meant to manually type in each addition of Ints in numbers??

loops.swift 
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below

while counter < numbers.count {


}

Hi Courtney!

Even though I have passed this challenge, it took me a little bit to understand what's going on! :D

You are doing well so far. Now, you will work inside of the while loop. Your task is to add every numbers in array to the variable sum. For this, use the counter variable :)

P.S.: A little extra - I wanted to solve this by adding always the first number of an array and then deleting it so in the next round I would get another number. It would have worked, hadn't the array been a constant :)
