I don't get it why the compiler stills says 'Make sure removeVowels' function accepts String and return a String.
My method signature is correct.
// Enter your code below
extension String {
func transform(_ function: (String) -> String) -> String {
return function(self)
}
func removeVowels(from value: String) -> String {
let vowels: [Character] = ["a", "e", "i", "o", "u"]
var removeVowels: String = ""
for character in value.characters {
if vowels.contains(character) {
removeVowels.append(character)
}
}
return removeVowels
}
}

23,970 PointsThis is how I completed this task; although yours looks like it will do the same thing
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
}
