You pretty much have it except it looks like you mixed up the local and external names for your parameters:

func getRemainder(value a: Int, divisor b: Int) -> Int {
  let remainder = a % b
  return remainder
}

I like to think of it as the first parameter name (or the outside name) is the external name that you use outside the function. Which makes the other name the local name that you use inside the function. Hopefully that clears things up.
