I am stuck at this step. Do I need to make a new variable named newValue? How do I add this into the loop?

Do I need to make a second while loop or just add it to the first? What is newValue and do I need to declare it as a variable somewhere first?

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

repeat {
  counter += 1
} while counter < 1




// Enter your code below

You don't actually need a new variable. When the instructions say "...where newValue is the value retrieved from the array", they mean you could refer to "numbers" and use the "counter" as an index to select a specific item from it.

But you may want to revise how the loop works so it will repeat the correct number of times. Task 1 included this hint: "You can get that number by using the count property"
