while.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++}
while counter < numbers.count {
print([counter])
counter++
}

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

Dont worry its a lot simpler. Should look like this

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++
}

any questions on how it works just ask

It should.Looking at your answer agian you actually did it in a way that should work as well you jsut have to many while loops. If you enter only your last while loop it will work too. Just tried it myself
