iOS Swift Collections and Control Flow Control Flow With Loops Working With Loops

loops:

Now that we have the while loop set up, it's time to compute the sum! Using the value of counter as an index value, retrieve each value from the array and add it to the value of sum.

For example: sum = sum + newValue. Or you could use the compound addition operator sum += newValue where newValue is the value retrieved from the array.

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

var newValue = 60
// Enter your code below
while counter < numbers.count { //if the value of counter is less than the count of numbers array
    counter += 1 // then add one to counter, and repeat loop.

    sum += newValue
}

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

var newValue = 60

// Enter your code below while counter < numbers.count { counter += 1

sum += newValue }

for number in numbers {

while counter < numbers.count  {

    sum += number

    counter += 1

}

}

Not accepting the answer. I get a error message: Bummer! Make sure you're retrieving values from the array inside the while loop to compute the sum!

with the code: for number in numbers {

while counter < numbers.count {

sum += number

counter += 1

} }

Very strange when i tried this on the code challenge it worked.

I just checked again now it worked. Check your spelling

I retyped it and it did not work, then I copied and pasted your code and still doesn't work for me
