20,157 PointsLet's use the two functions we created on a String literal.
Bummer! Make sure you call transform on a string literal and assign the result to the result constant i can not figure out why the function call doesnt work!
extension String{
func transform(_ argument : (String) -> String) -> String {
return argument(self)
}
}
func removeVowels(from value: String) -> String {
var output = ""
for char in value.characters {
if !(char == "a" || char == "A" || char == "e" || char == "e"
|| char == "i" || char == "I" || char == "o" || char == "O"
|| char == "u" || char == "U") {
output.append(char)
}
}
return output
}
let result = transform(removeVowels(from: Hello World))

let result = "Hello, World!".transform(removeVowels)
