I am having a difficult time understanding what I am doing wrong here. Please Help

I am most likely making this more difficult than it has to be and should most likely re watch the section. Any insight would be greatly appreciated

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

// Enter your code below

while counter < 7{
print(numbers)
counter++
}

while counter < numbers.count {
var newValue = numbers[counter]
sum += newValue
counter++
}

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

// Enter your code below
while counter < numbers.count {
  sum = sum + numbers[counter]
  counter++
}

I like doing it this way but all you needed to do is get rid of your first while loop and u have it correct.
