I dont understand what to do here ...

Now that we have the while loop set up, it's time to compute the sum!

Using the value of counter as an index value, retrieve each value from the array and add it to the value of sum.

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

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

sum += numbers[counter]
print(sum)

You simply need to move this line:

sum += numbers[counter]

To inside the body of your loop (before you increment the counter variable).
