Doing it right doesnt work

works in swift but for some reason doesn't work here

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 {
  newValue = numbers[counter]
  sum = newValue + sum
  counter += 1
}

The bummer " Your code could not be compiled. Please click on "Preview" to view the compiler errors." doesn't help since there is no Preview to click. So I tried to compile in a workspace an received:

loops.swift:8:3: error: use of unresolved identifier 'newValue'   

Declaring newValue at the top of the code fixed the issue
