I NEED HELP FOR WHILE AND DOWHILE LOOP PROBLEM, PLEASE HELP

this is what the instruction said, " Given an array of numbers, print out each number in the array using a while loop and the println statement. "

this is what i coded. " let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

var index = 0 { while index < numbers.count println (numbers[index]) index ++ } "

PLEASE HELP :(

while_loops.swift 
let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]


var index = 0 { 
while index < numbers.count 
println (numbers[index])
index ++
}

Your starting curly brace is incorrectly placed before defining your While loop. Your curly braces need to contain everything after the initial condition of the loop. 

let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

var index = 0

while index < numbers.count {
  println(numbers[index])
  index++
}

Good luck!
