Whats the code for both of these steps

Its very confusing

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

// Enter your code below

Look at the code below. For first task u only need to create a while loop which should continue as long as the value of counter is less than the number of items in the array, so we can use "<" and ".count" property for get numbers.

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

while counter < numbers.count {
       counter++ 
    }

For pass this task u need to use "counter++", BUT its not working in new versions of swift. So after this challenge you must use "counter +=1"

For the second task you need to compute the sum.

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

while counter < numbers.count {
    sum += numbers[counter]
    counter += 1

    print(sum)
}
