While loop Objective exercise

Hello,

I am getting following error message while attempting Objective exercise. I have pasted code below. Not sure where error is. I am incrementing counter variable inside the loop.

Bummer! Make sure you increment the counter variable inside the loop! If you don't, the code loops infinitely and the challenge times out!

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

// Enter your code below

while counter < numbers.count { counter += 1 }

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

// Enter your code below

while counter < numbers.count {
  counter += 1
}

Hi, your code should work, and would in Xcode. I think the Treehouse compiler is expecting you to use the (now deprecated for Swift 3) increment operator- counter++ - rather than the compound assignment operator as you have done.

Yep, I tried in XCode and it worked.

So I wasn't sure what wrong in my code and it is not working in Treehouse compiler.
