34,475 PointsHow to convert an array of characters to String in Swift? Stuck, please help.
Trouble not only for me. joined() didn't work.
// Enter your code below
extension String {
func transform(_ argument: (String)->String) -> String {
return argument(self)
}
func removeVowels(from string: String) -> String {
var output = ""
for char in string.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.joined()
}
}

23,970 PointsYou just need to return output, you do not need the joined(), you are looping through and returning the output
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 = "Hello, World!".transform(removeVowels)
