I don't understand why this code doesn't iterate over the whole array of numbers. //print(numbers[counter])

while counter < numbers.count { print(numbers[counter]) counter += 1 } The error says I need to iterate over every value in the array, and I learned from the video you do this with subscript from the array. What am I missing ?

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

while counter < numbers.count {
    print(numbers[counter])
    counter += 1
}

Hi Andres -

You are not including this part retrieve each value from the array and add it to the value of sum

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

}
