extension String {
func transform(_ function: (String) -> String) -> String {
return function(self)
}
}
func removeVowels(from value: String) -> String {
var output = ""
for char in value.characters {
if !(char == "a" || char == "A" || char == "e" || char == "e"

Your string looks like "Hello World!" missing a comma.
Here is an example of what you could do:
extension String {
func transform(_ someFunc: (String) -> String) -> String {
return someFunc(self)
}
}
func removeVowels(from: String) -> String {
var output = ""
for vowel in from.characters {
if ["a","e","i","o","u"].contains(vowel){
continue // If the vowel is in this array, it will continue the loop
} else {
output.characters.append(vowel)
}
}
return output
}
let result = "Hello, World!".transform(removeVowels)
Good luck
