Stuck on Swift 3 Collections and Control Flow challenge task 2

Question

I've changed my code multiple times but i continue to get the same error. I need simple explanations because apparently I'm not understanding Swift

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

Hi Stephen,

Your logic is absolutely fine but there is just a small syntax mistake. If you want to use multiple statements in a single line, you should separate them with a semicolon. As in your case, the two statements in the while loop should be separated by a semicolon because if you don't, the compiler would treat them as a single statement leading to an error.

You should always try to align your code properly as it improves readability and helps you to determine where the problem is.

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 
}

Hope this helps :) Happy learning!!!
