retrieve value from array

I am having trouble figuring out how to retrieve the values from the array

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

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

make sure to return the sum at the end of your function, also remember that your sum isn't number +counter. sum+=number. that way the counter number doesnt get added into your sum
