Basically, what you need to do here is to create a while loop that adds all the numbers together as long as the counter is smaller than the number of items in the array.


  • While counter isLessThan amountOfNumbers
  • Increase(sum, by: number(atIndex: counter))
  • Increase(counter, by: 1)

Just turn that into Swift code.

in case you are really stumped, here's my solution:

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

I hope this helps
