Dont know how to solve and not clear about how the repeat func works .

Hi can anyone help me out with this question ? I did my best but not understand what it is asking me .

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

// Enter your code below
while  counter < numbers.count {
counter += 1

}

Your loop is correct, you just need to add a line inside it to add the current element to sum:

sum += numbers[counter]

This will need to come before you add 1 to counter.
