help please

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

while counter < numbers.count {
sum += numbers[counter]
counter += 1
sum += 1

You're so close!! You actually have the answer, but then you also add one to the sum each time through your loop. Remove that, and you're good.

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

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