Please provide a working solution thanks
Challenge Task 2 of 2 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. https://teamtreehouse.com/library/swift-20-collections-and-control-flow/control-flow-with-loops/working-with-loops
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
while counter > 0 {
print(sum)
counter++
}
while counter < numbers.length {
sum += numbers[counter]
counter++
}

155,055 PointsThe Treehouse compiler produces the following error:
swift_lint.swift:11:17: error: value of type '[Int]' has no member 'length'
while counter < numbers.length {
^~~~~~~ ~~~~~~
You're very close: you have the right logical idea, but .length is not a property that the Int array is recognized as having.
(pssst... it does have a .count property that counts the number of elements the array has.)
Hope this helps!
