Code not getting accepted

Hi, can someone tell me why my code is not working for the code challenge? Thanks!

functions.swift 
// Enter your code below

extension String{
  func transform(_ function: (String) -> String) -> String 
  {
    return function(self)
  } 

   func removeVowels(from string: String) -> String
    {
    var output = ""
    for char in string.characters 
    {
    if !(char ==  "a" || char ==  "e" || char ==  "i" || char ==  "o" || char ==  "u" || char ==  "A" || char ==  "E" || char ==  "I" || char ==  "O" || char ==  "U")
    {
    output.append(char)
    }
    }
    return output
    }
}

Hi Vansh - You are missing calling the transform function to remove the vowels

On the string "Hello, World!", call the transform function and use the removeVowels(from:) function as an argument. Assign the result to a constant named result.

"Hello, World!".transform(removeVowels)
