iOS Swift Collections and Control Flow Control Flow With Loops Working With Loops

while loop

my code doesn't seem to be compiling. I don't know how to declare 'newvalue'

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 
{
counter += 1
var newValue = counter + sum 
sum = sum + newValue
//print (sum)


}

I think you need to place counter += 1 as the last statement in your while loop. This will also mean that on the first loop you'll be able to retrieve numbers[0] as the counter will be incremented after you added the first array value to newValue.

while counter < numbers.count 
{
  var newValue = counter + sum 
  sum = sum + newValue
  counter += 1
}
