6,204 PointsBasically, what you need to do here is to create a while loop that adds all the numbers together as long as the counter is smaller than the number of items in the array.
Pseudocode:
- While counter isLessThan amountOfNumbers
- Increase(sum, by: number(atIndex: counter))
- Increase(counter, by: 1)
Just turn that into Swift code.
in case you are really stumped, here's my solution:
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}
I hope this helps
