I'm not even sure what I'm supposed to do here. Helppp please!

What is it even asking me to do here?

while.swift 
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0

// Enter your code below

while counter < numbers.count {print (numbers[counter])
counter++ 
}

Maybe try this

let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0

// Enter your code below
while(counter<numbers.count){
  sum += numbers[counter];
  counter++;
}
