Stuck on :: Working with Loops, Challenge Task 2 of 2

What am I doing wrong.. Am I supposed to replace the previous code from Challenge Task 1 with a whole new code?

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

// Enter your code below

while counter < numbers.count {
  print(numbers[sum])
  counter += 1 
  } 
while counter < numbers.count {
  sum = sum + numbers[counter]
  counter += 1
  }

Hi Rikki - You have the answer on this one you are just including extra information

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 += 1

}

I had an issue with this for so long. Yes, you will have to replace it otherwise it would not work at all.
