iOS Swift 2.0 Collections and Control Flow Control Flow With Loops Working with Loops

I need to get each value from the array and add it to "sum" while using "counter" as the index.

Feel like i've tried everything

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

// Enter your code below
while counter < 7 {
  print(numbers)
  counter++
}

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

Try this

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

// Enter your code below
while counter < 7 {
  sum += numbers[counter]
  print(numbers)
  counter++
}

because counter is already increasing, you can use its value as an index for numbers to add to sum. Hope this helps good luck!
