Struggling with this particular line of code to get it to work.

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 += 1 }

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

Actually, all you need to do is to hit enter before "counter += 1" so that they are on different lines, that's it. What you could do to clean it up is to do it like this:

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

But to get it to work you only need that line break.
