Not entirely sure how to code out the while loop challenge

Not sure how to code this one out, I understand what is being asked. But not sure how to put it ito code.

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

// Enter your code below
while sum + counter[6] {
    counter < 6
}

Hi Michael -

The first part of the loop starts with a while statement that executes when counter is less than the count of numbers. In the body you are adding 1 to counter. For the second part you are just adding it to the sum array. Let me know if that makes sense :)

1st Task

while counter < numbers.count {

counter += 1
}

Second Task

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