stuck after the loop

hi guys! I was able to setup the loop just fine (I think) but I really don't know how to do task 2 and sum everything together. Do I need another loop to do that?

thanks so much for your help

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

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

You need to add your sum addition inside your while loop so you can access all numbers. The 'number' you add is the current position in the array.

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

// Enter your code below
while counter < numbers.count {

    sum = sum + numbers[counter]

    print(numbers[counter])
    counter++
}
