I don't know how to retrieve all the data in the array! I am stuck in this coding challenge, please help me!

When I am writing my loop y don´t know how to retrieve an add data.

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

while counter < numbers.count {
     sum = sum + numbers[0]
     counter++
}

You can use the counter variable (which is increasing by one every time) to access each variable in the array. To access the first variable, you'd do numbers[0]. For the second value, you'd do numbers[1]. Since counter is going from 0 to the number of values in count, you can simply replace those bracketed numbers with number

sum = sum + numbers[counter]

Your sum statement should look like this: print(sum[numbers])
