Closures Challenge

Question

I'm stuck with Challenge Task 2 of 3 of the Closures 2017 course.

The code is working perfect in the playground but i can't pass the challenge. Whats the issue?

functions.swift

// Enter your code below
extension String {
  func transform(_ function: (String) -> String) -> String {
    return function(self)
  }
}

extension Character {
    var isVowel: Bool {
        let vowels: [Character] = ["a", "e", "i", "o", "u"]
        return vowels.contains(self)
    }
}

func removeVowels(from string: String) -> String {
    var newString = ""
    for char in string.characters {
        if char.isVowel {
            newString += String(char)
        }
    }
    return newString
}

You seem to have misunderstood the objective of the task. The removeVowels function is supposed to remove the vowels from the string it is given and then return a string without vowels. Your code does the exact opposite. In addition it only deals with lower case letters. It would fail if the string contained an uppercase vowel.
