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

Task to of loops

Could anyone please help me with this. The question states that we should use the value of counter as an index to calculate the sum of the values in the array. Thank you

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

// Enter your code below

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

Hello Johan,

this code works, what is the problem?

Hi Gerald

This is the complete question, my answer gives me an error and I am unable to progress.

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.

Thank you

That's strange, I don't see any problem with the code. On my end it works fine.
