Task 2 Help

Confused with the second question on Loops. Can someone please explain to me how to get through this, please.

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

Hi, the second while loop you've written is fine, you just need to change it from numbers to numbers.count. See below:

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

// Enter your code below
while counter < numbers.count {
  sum += numbers[counter]
  counter += 1
}
