I cannot figure out step step 2 of 2 on this.

I cannot Figure this out. I have read through the rest of the answers and I still cannot figure it out.

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

Hi Marley - There is not need for the first while statement you have

while counter < numbers.count {

    sum += numbers[counter]
    counter += 1
}
