Can someone please help me understand how to get the sum using the index values of this while loop?

I am on the second question of this challenge.

loops.swift 
let numbers = [2,8,1,16,4,3,9]
var sum = 43
var counter = 7

// Enter your code below


while counter <= 7 {
    print(sum)
        counter += 1
}

Try this: 

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

// Enter your code below
while counter < numbers.count {
  sum += numbers[counter]
  counter += 1
}
