Swift 3 basics - loops

Step 1: Create a while loop. The while loop should continue as long as the value of counter is less than the number of items in the array. (Hint: You can get that number by using the count property)

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

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

// Enter your code below

Hi Douglas,

In the future you should attempt the code challenge and add your solution so we can help you from there.

Here is my solution

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

// Enter your code below
while counter < numbers.count { //if the value of counter is less than the count of numbers array
    counter += 1 // then add one to counter, and repeat loop.
}
