The issue is that you have the local and external parameter names the wrong way around. External parameter names comes first then the local name.

So you have to switch the names around like this:

// external and local name swapped
func getRemainder(value a: Int, divisor b: Int) -> Int {
  // value and divisor renamed a and b due to name change above
  return (a % b)
}
